Now i explain: Quite simple, just post the game that looked awesome/impressive/had lots of potencial but came out to be a big disappointement and your reasons for the pick..or not, people have lifes after all.
Gta4-why?the other gta games were a blast, gta4 showed a lot of good stuff but lost all the gta essence for me.
Assassins Creed- Great graphics,swords, assassins, good story but the missions..omg boring as hell!
I bet a lot of "HALO3 HERE!" will show up :P
