Reply to above. If pie-rats can make the game DRM free easily then i'm guessing Beth/MS could do so and add galaxy stuff. Also they don't even need to sell that much....just more than what it costs to set everything up and bring it here.....which I am guessing they could do easily.
Thing is: the "pie-rats" unofficial DRM-FREE version likely won't support Steamworks and/or GOG Galaxy features. Yeah, it'd work and all - but it'll lack features. And for that alone, that doesn't make the greatest of analogies. If you mentioned older games that didn't have this modern-stuff in both Steam and GOG versions; then you'd have the 1-to-1 fair comparison.
When you talk modern games, a lot of them support Steam-works for Cloud Save, WorkShop, Achievements, and other stuff - and when it comes to GOG, Galaxy implementation will take effort, time, money, resources, and whatnot. If they make a game w/ a lot of Steam support for Steamworks and a lot of those features - yeah, they'd have to strip them out of GOG Version and then add Galaxy support for new features.
Skyrim. You'd need a company like Bethesda, Zenimax, Microsoft, or whomever - to sink $, resources, time, man-power, and whatnot into getting this game onto GOG properly; likely w/ proper GOG Galaxy and its features supported. This is why someone would buy something like a modern game on GOG Galaxy. If a modern game comes to GOG lacking a lot of Steam-features, who's going to buy this? This version will be seen as inferior and feature-lacking. Also, if M$, Zenimax, Bethesda are going to bring it to GOG - it's gonna make sales, or...why even bring the game here?
Look, we all want as many titles hitting GOG as possible w/ its DRM-FREE attitude and all - why would I buy this again? I already own Skyrim: LE and Skyrim: Special on Steam.
A GOG version here might be a better sell to someone who doesn't own Skyrim: LR or Skyrim: Special at all.
About ME: LE - check the IGN videos and the game-notes - they've both noted what will be charging in LE. And namely, like you said, it's graphical changes and/or improvements; and there's other changes too.
About Remasters, Re-Releases, Etc. ME:LE will be a great option namely for those who ain't played ME Trilogy before, as it's everything (except Pinnacle Station DLC) there all in one big old package.
For people like me who own ME1,2,3 and all its DLC's - eh, this might be a tougher sell. But, the selling point of ME: LE for me would be the changes to ME1 might be more in line w/ ME2, combat-wise and feel-wise. If they ME2'd basically ME1 here, that could be a major improvement, as combat will be less clunky in the LE version of ME1.
Also, nobody is forcing anyone to buy remasters, releases, or anything. So, if you have an old version and don't like what the new version's doing and/or think it's a cash grab - free market, just skip it. Or, if you have an interest - buy it when it gets cheaper.
