1) I had a boxed retail game once that i redeemed on an older steam account. Now that "remove game from your account permanently" exists, if i manually remove it from old account, can i use the retail key on my current one to claim game there?

2) Let's assume i preordered a game and for various reasons, i refunded (crappy, buggy, broken, not even working and launching port). Let's assume that i figured out how to make the pirate version work well and i would be interested in rebuying (some time later, on big discount). Will i get the preorder exclusives on second purchase, since i did preorder and game had them for me, at start?

1. It is not actually removed from your account. It's a more extreme version of hiding the game.
You will not be able to reuse the key.

2. Probably not unless those are contained in your save file and the game is set up in a certain way.
Generally I would say no you will not have the preorder bonus.

What would be the point in re-funding a new game when patches are likely fix it?

Haha - I was thinking, "Man, Bradley has put out some serious hate for Steam over the years, and here he is asking about a game he bought... on Steam?" Must be something you REALLY wanted.

Hope you get it resolved - in a legal manner (not griping about the pirate version for testing; I understand your choice to try the new version that way). Crappy products, um, suck.

I think it is unlikely you would get the preorder bonuses back, but these are questions better asked of Steam support than gamers on a forum for a competing store.

Then Bradley should know better than to support this pre-order bullshit. :P

If you aren't 100% sure that a dev will deliver a quality, polished product, then hold on to your money until after release.

Yeah. I NEEDED this one game so bad... And damned thing won't be released anywhere else, not even simple, good old retail... It's just my luck. Sh*tty as ever... Yes, this is the case, i asked there and others already bought it back, after refunding. Sucker-bait, a.k.a. "preorder exclusives", gone. Whatever is gone, is gone... Since the game was a broken cash-grab, i won't miss it anyway... Ahh you are telling me...! First time in all my gaming life, i broke the NEVER-PREORDER taboo on Witcher 3... But it turned out solid gold of a game... Plus those idiotic devs promised public that game would be perfectly optimized for pc, it being developed there primarily and it having the same quality and performance on any media it was released for... Not my fault... I merely believed what they stated in public! Now i will sit back, enjoy my pirated version, since second patch is reported to break some things while trying to fix previous issues (and everyone knows that Steam unlike Galaxy doesn't have rollbacks to previous versions) and wait for a BIG discount, enough to "compensate" me for those liar, crooks, and other cosmetic descriptions, people. I should have figured they were consummate lowlives their publishers, though, my fault, i even "accused" them here on the forums before, because they wronged CDPR and embezzled from them a hefty sum that should have been sent to them, a long time ago...

Most likely a re-bought game is considered as a separate 2nd sell, independent of your account previously having another version of it as preorder.

I'm curious; what devilish game is it that turned you upside down? :D

Wait, am I missing something? You, the anti-Steam ideologue, bought Witcher 3 on Steam? That's beautiful, if so.

Anyway, preorder bonuses are sort of a thank-you for paying full price so the company can pay their employees. Still, since you're a peg-legged, morally bankrupt sea devil, you should find the old "exclusive content" mantra for PC to hold up - if you want the content, it's there. Pay for the game, pirate the extras, and maybe play a little game of cat-and-mouse with the client to make sure it doesn't phone home and "fix" your installation.

You got that wrong. I said i broke my preorder taboo for witcher 3, but never did i say it is the game i bought on steam... About the rest, it made my night!

If it helps, I don't use steam full stop. I don't pre-order full stop. You be amazed at all the problems I don't have. Learn some patience. Witcher 3 will be on my radar some years down the line, when it is complete, patched to working, not before, nor with any other game where they try all this nonsense on.

And how many games are unoptimized in comparison to the ones that are?

So... what game is it you're wanting to buy and not miss out on the preorder bits? GODUS? Batman Arkham Knight? Raven's Cry? :)
