Does preordering a physical copy get you anything thats non digital (sourcebook or anything like that)?
Like, do I get anything tangible with a physical copy, other than the box?

Unless they made changes, no, you do not.

Edit: Well, this would suggest, I'm wrong:

https://www.gamespot.com/articles/cyberpunk-2077-pre-order-guide-new-release-date-bo/1100-6459539/

Edit 2: To summarize:
Physical editions (including non-pre-orders) include the following physical items:
-soundtrack CDs
-World Compendium of lore
-postcards from Night City
-map of Night City
-stickers

If you get the physical collecter's edition (again including non-pre-orders), add to that:
-Collectible steelbook
-10-inch statue of V
-Hardcover art book
-Metal pin set
-Quadra V-tech metal keychain
-Annotated Visitor's Guide to Night City sealed in NCPD Evidence Bag
-Embroidered patches
-Collector's Edition box

The only physical pre-order bonus, I've found so far is:
-Samurai Medallion, but only if you are a member of GameStop's PowerUp Rewards program and pre-order at GameStop

Not everyone has the space or the need for physical stuff.

That's kind of two questions:

Why would anyone pre-order? Because they have more money than brains, and are so addicted to the tiny dopamine injection they get from spending on their hobby, that they cannot control their impulsive urge to order asap.

Why would anyone buy a digital copy? Because, if I am not mistaken, they are actually cheaper than physical copies, depending on your location and retailer.

Firstly, you are mistaken, both physical and digital are the same price here. Second, last game that I 'pre ordered' was in 2011 which I recieved as a birthday gift. It's hard waiting 9 years in between my 'dopamine hits'. Actually, as the 2011 game was a gift, this must be my first 'hit'. Good theory though.

Like I said, I think it depends on your retailer (and location). For instance here, if I pre-order a GOG key off of Gameshop right now, I'm €10 cheaper off than ordering via GOG itself. But for €5 more, I can pre-order a physical copy at Mediamarkt...

As for pre-ordering:: Look, it's your money, so you should spend it however you like! I just don't see the point in pre-ordering anything, ever. Because you can never truly be certain of how the product will change, that the company won't go bankrupt, etc. etc. Pre-ordering is like giving a company an interest-free loan, or investing in the company for nothing more than the promise of some bonus item.

The dopamine theory is not my own, it's been bouncing around for years now. I believe, the idea cropped up after someone showed a correlation between dopamine activity (or perhaps reuptake inhibition?) and investing in a hobby (e.g. buying new equipment, subscribing for classes, etc.)

Anyway, you do you. But it's good in general, to reflect on value propositions before making any purchase, let alone luxury ones ;)

I preordered the CE, because i wanted a chance at the CE. There's always a chance to cancel it, so no risk.

But i also know my expectations for the game will be met as they are realistic for a CDPR game. I want good story with interesting quests. That's what i got with Witcher 3, that's pretty sure what i will get with Cyberpunk.

I kind of went on the defensive, because actually I agree with you. Pre order IS stupid. Normally I would be on your side 100%. Im looking forward to a few games that are upcoming;
Bloodlines 2, System shock remake and SS3...
I would never preorder any of these, too many unknowns. I wanted to show support to a company that is making the right decsions in my opinion, regarding microtransactions, dlc quality (based on W3) etc. That's why I preordered. In an industry that sucks (AAA games), these guys are doing everything right IMO. Giving them my money early is a way of saying "I support what you are doing, keep doing it".
Yes it's an unknown, but it's a calculated risk based on their past performance. Even though I'm just as excited for bloodines 2 potentially, there's no WAY I would preorder that one. No reason to. See what the reviews say, see if they've including microtrans in single player, season pass day one DLC, launchers...etc. Then I'll decide to buy or not. If they have included anything I feel is shady or unethical, I'll pass. I'm still waiting for them to drop SP microtransactions and DRM so I can finally play DXMD but not holding my breath ha ha

Purchase the physical copy of the game. Maybe there is a map of Night City inside the box and maybe also stickers or stuff like that. A GOG code is inside the box to activate and play the game here on GOG.

That's my point though. You cannot be sure that there will always be a chance to cancel. If the company goes bust, customers are the last party that will ever see any of their money back. And how sure are you that they will allow you to cancel your pre-order, if it turns out upon release that they have made content decisions that make you dislike the game? You can't be sure, so why risk it.

CDPR is a wildly different company from what it was a few years ago. It is not the same company that made Witcher 3, let alone Witcher 2 or 1. The changes in company policy and staff are, in my opinion, not one's that inspire confidence that they will deliver on par with any of their previous titles -- perhaps especially as far as story is concerned. +1
I understand. I strongly disagree about whether CDPR is currently doing things right and should have their behaviour reinforced by positive conditioning through pre-orders. But as you say, that is an opinion; and everyone should make the calculation of risk and value for themselves, to arrive at their own conclusion on whether they should spend their money.

For both of your sakes, I hope Cyberpunk delivers what you're looking for. For my and their own, I hope it fails to the extent they are forced to revise their recent policy changes.

I'd be interested to know what those changes are, but even so, they're surely better than the current crop (EA, Activision, Bethesda)

I would argue they are not better than EA, Activision, Bethesda or any other company, with the possible exception of Epic (the company that spies on people for the Chinese government), 2K (the company that stalks, blackmails and physically abuses family members of YouTubers who cover their games) and Paradox (the company that is banning players for saying 'Deus Vult' or 'Allahu akbar' in a game about the Crusades, the previous installment of which included those same phrases).

Here are a few examples of CD Projekt's current trajectory and why I won't give them any more money until things change:
-CDPR removed the options to play as 'male' or 'female' from the game and replaced those with selectors for 'body type' and 'voice type' which can be mismatched. Then they lied about this having been changed.

-CDPR's official community managers on the CDPR forum and Steam are censoring any and critical questions about Cyberpunk 2077.

-GOG deleted their 23 October 2018 tweet: "Classic PC games #WontBeErased on our watch. Yeah, how's that for some use of hashtags?"
-A day later, they apologized for it: "Yesterday, we posted a tweet containing a trending hashtag as a pun. The tweet was neither intended as a malicious attack, nor as a comment to the ongoing social debate. GOG should focus only on -games. We acknowledge that and we commit to it."
Then they went full retard and fired their twitter manager at the time, Sean 'Linko' Halliday
-And finally they smeared him publicly to make sure he could not find employment at a rival dev.

-CDPR deleted their 20 August 2018 tweet: "Did you just assume my gender?"
-A day later, they apologize for it: "Sorry to all those offended by one of the responses sent out from our account earlier. Harming anyone was never our intention."
-Then CDP changed its hiring policy (also for CDPR, GOG and other subsidiaries) to artificially increase the number of female, immigrant and alphabet soup employees.
-There are rumors they also forced all their staff to go through some sort of sensitivity training.

-GOG also designed Galaxy 2.0 to be much more privacy invasive than 1.0, and is forcing everybody to 'upgrade'.

For any company I think this is absolutely egregious behaviour, but for a Polish company even more so. If you know any Poles, you'll understand what I mean. They've been through decades if not centuries of persecution and censorship, and have always rather broken their backs than bent down. Now their biggest games company stabs their ancestors and tradition in the back, by employing the same political persecution and censorship. It's an outrage.

Wow! Didn't know some of this stuff! Gone are the "golden days" of gaming, eh? :(

+1

Can confirm this personally, as I've witnessed even comments that contained only a mention of censorship being deleted literally within 5 minutes of being posted...

This is just terrible, to destroy ones job opportunities in the industry like this. :( As far as I know there's a similar practice within Japanese Corporations, once you're in one your there for life and once you cross them, no matter which way, no matter if intentionally or not, you're "burned" in that industry for good.

Can confirm reading similar things on the net. When you change from merit hiring to politically biased hiring you're going downhill faster than you can say [choose a censored, politically incorrect phrase of your liking]. xD

This is especially unfortunate for me, as GoG.com doesn't display correctly (most of the time) in any of my three browsers... Meaning once Galaxy 2.0 replaces 1.x I might not be able to access GoG.com at all.

Very true (especially if you know about events during WW2 and after). I guess at this point it's not a Polish company any more. ;(
