Steam is Satan's vagina .

This is a really good analogy.

I buy games eyes closed on gog. Reluctantly on steam, where i have to carefully check drm traps, etc.

And i carry my gog games in my laptop, with no worry of being at a place without internet.

Which is better: GOG or Steam? There's only one way to find out....

FIGHT!!!

TBC, Steel Cage, or Hell in a Cell?

Satan's a chick?

Gabe Newell vs Guillaume Rambourg? That'd be one I'd look forward to.

Steam - bigger and in some cases better selection, generally MUCH better sales, the Steam client is probably the best there is out there, Linux support (for some games, though the list continues to grow), obviously much better for online multiplayer titles, especially ones by smaller companies who can't afford to run massive servers, easier and faster to download and uninstall games and more convenient for games that receive continual updates and patches (whereas GOG you have to manually install patches and sometimes the games themselves every time, but that's the nature of being DRM-free).

GOG - NO MANAGEMENT OF RIGHTS FOR TEH DIGITAL!!1 Seriously though, that, far better selection of classic titles (hope they continue to keep up this trend), MUCH better customer support (as in, actual customer support at all), keeps games continuously updated to be compatible and stable for modern hardware themselves (unlike Steam where everyone is at the mercy of the developers and publishers to fix something), better quality control (even the bad games here are still functional and can be considered "games" - a WarZ or Day One: Garry's Incident would never happen here, much less shovelware / useless cash-in licensed games based on recently released films - also note that when Dark Matter was removed from both services and everyone received refunds from both places, the game came back on Steam but several days later with barely any changes except a short CG cutscene to replace the ending's text crawl, whereas it has yet to come back on GOG), an actual refund policy, no regional pricing BS, is maybe somewhat friendlier to certain indie games even if there aren't as many as on Steam (a lot of indie titles that got released here had to go through Greenlight to get on Steam, and in some cases still have yet to get Greenlit, Richard & Alice comes to mind).

What's Steam?

Steam:
- save synchronization, latest patches auto-apply (reinstalled the OS? Your saves are not lost);
- native Linux support for some games (including World of Goo, Kerbal Space program and others);
- multiplayer-based games (Dark Souls, Call of Duty series and others);
- games from certain publishers (Bethesda, EA and others);
- achievements (if you are into this. They don't actually do anything, it's a purely social feature);
- regional division (some games may be cheaper in your region. Some games may be more expensive/unavailable for your region);
- built-in workshop (no need to look for mods elsewhere)

GOG:
- games can be played anywhere, at any time (no need for internet connection for anything except the actual installer download; you actually own the game);
- tech voodoo (I don't know what GOG does with the games, but almost all of the games on my shelf I successfully installed and ran in Wine - even those, the original (disk) versions of which had certain issues. This point is more IMHO/subjective than others though);
- games Steam doesn't have (Neverwinter Nights 1&2 for example);
- community (tastes differ, but I find GOG community rather civil while the other one is... well, feel free to see for yourself and choose which is more to your liking);
- "one world, fair price" (if the game is on GOG, it is available for purchase anywhere; if it is discounted, it is discounted everywhere at the same rate);
- modding freedom (there's no client to overwrite your installation while "updating" it so you can install any mods, whether they are listed here or not);
- additional content (every game comes with something added besides the installer itself, be it a set of avatars, OST, wallpapers or something else)

Both lists are incomplete, points may be added in favor of each of the alternatives, but this might give you the general idea of what is what.

off-topic: I wonder how would Steam deal with users who registered from ISS? What region would they choose for them? Not that this is likely to occur anytime soon, but I'm still curious.

I should know better than to answer a post a like this but just out of curiousity, please provide the main argument that would back this up?

There isn't one of course, a true videogame lover would get the game regardless of any possible inconveniences he may endure, since it's all about the game.

I'm not sure why it often seems to be GOG vs Steam or Steam vs GOG. I use a variety of stores myself including:

Steam - I've been there since its inception and own more games there than anywhere else. I like the client features and social aspect of what has become more than just a store but a service as well.

GOG - I own a large number of classic games, many for Mac OS X here on GOG. The majority of these were not and in many cases still are not available elsewhere. This place became THE place to get classics for me. It is certainly a plus that all these old and older games are DRM-free and the soundtracks, etc. are nice too.

Mac App Store - I get games here that are not available elsewhere for Macintosh. I'm very happy with the service too which keeps the games updated, downloads and installs them for me, etc. but does not run any client software when I play them.

Origin - Very sparse Mac offerings but good for a few games on sale, The Sims of course and a few Windows games not available elsewhere.

Blizzard - World of Warcraft, StarCraft II, Diablo III & of course expansions to these as they release.

Amazon.com - Stuff like Myth II Soulblighter (used) so I can set it up in source port to play on my Mac. It's a good place to find stuff like this plus I buy all my console games here, some music, etc. I like Amazon a lot.

Humble, Groupees, Indie Royale, etc. - for awesome deals on bundles of course.

Direct from developer - I just got an awesome Mac version of Ultima III for OS X direct from the guy who made it. Every now and then this is the way to go for special titles.

Looking at the GOG sales thread I see people use all of the above and more such as GamersGate and Desura which I don't use myself. It's not that I have anything against them but my needs are already covered by the many logins I have now.

Who shops at just one place really? Even if you prefer GOG or prefer Steam I would think a small minority limit themselves to a single store. I think most people are more interested in the games themselves and the prices for them than which place they come from when it comes right down to forking over the cash.
Yep. You nailed it. :D
