wolfmanrip: Ok i will provide a clear example.
Beamdog releases Baldurs Gate enhanced edition but they don't give anyone else the write to release their version of that game.
If steam or GoG made their own enhanced edition of baldurs gate and sold it then would that break copyright laws?
Neobr10: No, these are totally different things. GOG just patches games to work on modern systems, they dont add anything to the code or anything. And most of said "patches" come from the community itself. If you look around there are many unnoficial patches and workarounds for older games with compability issues. GOG just makes it much easier than having to search through the entire net for fixes. It already comes pre-patched and fixed to work on modern systems, something you would not get if you bought in retail. Again, GOG doesnt create anything, most of the time, they sell the games exactly the same way they get from publishers, they just patch, fix and then get it into an installer package of their own. There is no copyright involved, since they pretty much just get permissions from publishers to sell their games here. They dont own these games, publishers do.
Now with BG Enhanced Edition its a whole different issue. BG EE will not be the same game with higher resolutions, it will be a complete remake (same with MDK 2). Beamdog is doing this (Overhaul Games, an internal division of BD, to be more precise), and they probably will have exclusive right since they are the ones making the game. It could be released on other platforms if Beamdog allows it, like MDK 2 which will be released soon on Steam from what i have heard.
Note that BG EE is not BG patched up with compability fixes (like GOG's version), but a whole new game, which will even have quests not available in the original.
I heard that some games in Gamersgate even use GOG's installer.
Would not be too sure about BG EE. I read in different places from the start its basically a HD reskin job + SOME new material including quests and a few Chars. And making it work and fit properly first and foremost on tablets blah blah. Its not something radically new.
Unfortunately (from my view) they are also looking at trying to do the same with PST :/
