Is it just me or do a lot of people not understand what the OP question was asking?
Seems like it's turned more into a "I don't like game x" rather than "I didn't understand why people were excited for game x".
My vote would be Dead Island. I mean yeah, that trailer was epic, but the game was never going to be like that, the only real press releases prior to release painted the game as a fairly generic zombie game. Really couldn't understand why people were so excited about it.
Kingdoms of Amalur: Recking is one that I really don't get.
There was a big hullabaloo about this game because of all who was working on it and it turns out that it was 'meh'. I wasn't a huge fan of how the game looked, and the combat didn't rock my world when I played the demo when I heard just about everyone tell me how great it was.
I`ve never understood why fans get so hyped for Mass Effect.
I mean I loved the first one back in like 2008 don`t get me wrong, and I preordered and sort of enjoyed the second one. But never would I have gotten to the point where I start petitions and lobby with Bioware to change the fucking ending to one of the games in that series. I never considered the series particularly well written, nor did I find it`s gameplay as intriguing as other titles released around the same time. I mean don`t get me wrong I enjoyed both ME1 and 2 when I played them but they are the science fiction game equivalent of potato chips really.
I mean it`s insane. I don`t even consider the original Mass Effect Bioware`s best game, not even in recent years. I didn`t even buy ME3 because I didn`t consider it worth my time, but apparently people treat Mass Effect almost like it`s their entire religion.
