Sure. Let's pretend that if Fallout 4 or Witcher 3 released this year that both wouldn't have completely overshadowed Dragon Age. The only reason it won GOTY is because so many other games dropped the ball this year.
Yeah, let's pretend a game that doesn't exist and game that hasn't even come out yet and nobody has played would overshadow a game that people are playing now. Definitely BSN logic right here lol.
Yes, a lot of AAA games are disappointing this year but that doesn't take away as to how good DAI is. Many hold Skyrim as the gold standard for WRPGs in recent years and I think it's a better overall game than that. Perhaps it's unfair to compare them since they're so different but I'm talking favorite RPGs that are popular opinions. So no, regardless what came this year it would still have high praise. This is Bioware's first attempt at a game this big and their world is already more interesting than any Bethesda game. IMO of course but I did absolutely love Morrowind and Fallout 3.
I'm thinking Witcher 3 is going to be GOTY in 2015 but let's not pretend like everything is peachy in that game right now. It's already on their second delay and they have ran into development problems by losing several lead devs in the middle of development months ago. It would be
ignorant to crown it as a better game without playing it. For all we know the ambition might be too big for CDProjekt to handle. I have confidence they will but I've seen many AAA games run into similar problems and it didn't end well(see a recent example in Destiny). Destiny ended up at a point in development where they realized their ambition was too high and they had to scramble for a year to redo certain parts. Read the story on it. That's why we ended up with the disappointment(or at least a lot of players feel) Destiny ended up being.
I'm definitely anticipating Fallout 4 though! Been my most wanted game for awhile now.
