i think "short" is only what you think is short. playing a fuckfake game for 12 hours is damn long i can tell you :)
gears was realy short, on easy co-op it is realy quick over. but i completed it now 5 times wich is also 60 hours of playing + the online possibilities.
so to say it in short, i rathe have an 10 hour rollercoasterride with the adrenaline going rocket high. then playing a 60 hour rpg wich i dont understand and spend more time walking from town to town then the story.
life isn't complicated, just face it simple.
