Halo 3

Can't let that happen now, can we?

Update: From most people I know who have played it say its single player game is very short but decent. I played the splitscreen mode a few times on a plasma at work and it didn't impress me too much.
One guy put it like this:Halo was great. Halo 2 was ehhh. Halo 3 was ughh.
I guess I'll have to rent it to find out. I still want to know how it ends.
