The series is ok. Not at all very origional, and yet compelling and very addicting. It IS a damn good game. IT is a pitty Micro$oft bought out bungie, as I would have rather seen the series more distributed as it should be. Coorperate bastards.
The nice thing about Halo is that anyone new to games can pick it up and run to with it - hands down. Some people I used to work with and I are constantly throwing halo parties and such - so yea - plenty of fun.
