I played all of the originals like 1-5. I played ODST and Reach, too.
I would say I played Halo 4 the most since I didn't own any of the Halos until the 3rd one. I prefer the 2nd one the most cause of dual wield.
FYI, if you didn't already know. The campaign is a piece of crap or at least the ending was.
When you get it, let me know. I don't want to get raped no more.
