But GOG people will just think it's the same anyway because everything on GOG is better.
That's a case-by-case thing. Gamers should read the forums, listen to gamers, and figure out what version's the one for them.
Sure, it's nice to be DRM-FREE on GOG versions. That often can be easier to mod, less DRM issues, and other nonsense that can crop up w/ other versions. But, sometimes it's the fault of the developer and/or publisher, depending on how they actually decide to support the product (or not support it).
They should test EVERY version properly - taking into account game-clients, DRM, overlays, and things of that nature. Sometimes, I really think these dev's or pub's are lazy - just make a version for GOG, thinking it'll work on Steam no problem...yet, it doesn't w/out working around it (see Wiz 8 Steam-version).
Take
Deadly Premonition PC, for instance - Steam vs. GOG. Steam-version's got a leg-up on GOG.
I have the Steam-version only, BTW.
Steam-version is (still) one patch ahead of the GOG version. Who knows if the GOG version will ever get patched, the way it's going. That's VERY important - and gamers should know that.
Regardless of what version - it's a horrible port. Check both GOG + Steam forums. The game runs like garbage and likely will eventually crash; you're going to need DPFix to stick it above the locked 720p; and you'll likely need to a program to make it Large Address Aware so it runs better + takes into account over 4GB of regular RAM.
Great game, though. It's too bad that it's riddled w/ such a bad port; and crummy support from the company that ported it.
