i like the master chief character. he is like clint eastwood in all those man-with-no-name western movies. He is tough, and doesn't need to say much because everyone knows he's a badass.
like kona said, it would be cool if they mixed it up a bit and brought another main character into the story. or a prequel game; something that developed the story a bit before CE.
i wish they changed the way the game 'played.' i am not sure what i mean by that, but there is something about the way the game handles, and i think it just might be the weapons, that i just don't like; it isn't bad, i just like the way other games feel, better, like the cod games, and more recently, vegas 2. it is like some art, it looks good and some people like it, but others don't (i mean like vase of flower type picture, not obvious offensive 'art').
There is something i just don't like and it keeps me from enjoying the game. maybe, besides just the weapons, it also has to do with the way you can never fight just a few enemies; it's like you vs 50 enemies everytime, and it is never broken up...it is the same encounter again and again. and the flood, i think that just ruins the game...there is to much of it.
I got the story from the games fine, i just like the pre-story. halo is kind of like star wars iv, it just kind of starts in the middle of a war. there is a little back story, but not much about MC himself or other spartans. which, i hear, is where the books come in.
