ok ok ok i hate to say this, but honestly. The best story line i have ever played that kept me hooked was halo. It was such a driving game and just when you thought you were gettiong some where they throw the flood at ya. The music was awsome, the cut scenes were fantastic, and come on the graphics.. blow everything away on all the other consoles. Yes I know i am sounding like an xbox fanboy. Honestly though, if you played this game, you have to say "yeah I have this memorable part when such and such comes at you, and i use this such and such weapon". A game that make's you remember what you used or what strategie you used to get through a certain part is an awsome game. We all have those moments on halo, atleast for those of us who played it.
