I like these close minded debates.
Whats better for you and why?
For me I'm a Halo person but I'm not a close minded fanboy, I think a little realistic one shot fast paced war-like atmosphere that COD provides is real nice too. Depends on the mood. But jet packs and shields and plasma grenades are good eatin.
But sometimes having that realism is nice to play though, but campers their are a hell lot worse and more effective on COD which is annoying.
But it's not about me, it's about you.
Both great games, both have flaws and improvements.
