which game is more popular Halo or call of Duty never played any of them but I heard they are real good games I've seen Call Of Duty for Wii once at GameStop didn't really get it though because I don't play those games I just want Your opinion 

Honestly, They are both popular. They are both great games to play, but it all depends on who you ask. If you ask someone like me, who looks at both games as great games, then you'll get a fair answer. On the other hand if you ask a Call of Duty fan, he'll say that Call of Duty is better and Halo sucks, and vise versa. So I think you should be asking someone who likes both. I like both games, and I've played all Halo games, and all but the first two Call Of Duty games, and I enjoyed playing all of them. I remember when I was 10 or so I'd play Halo 1 all the time, It wasn't till later that I got Call of Duty 3 for Xbox 360 and that got me to like Call of duty. So basically, when you're asking which game is more popular, it all depends on who you ask. It also depends on how you like to play, because play-styles of Halo and Call of Duty are somewhat different.

I hope this helps

thanks for your answer

I have played them both, and I like Halo Much more, because I like things either sci-fi, or fantasy. I'm not a fan of things like games taking place in the present time on earth. It's just not my thing.

undoubtably call of duty is the most "popular" but personally i dont care about either.
Halo is unrealistic and repetitive, i would say dull, its overhyped because 360 fanboys want to imagine theyve got great exclusives.
Cod is the same game every release, im not paying full price for the same game anymore, enough.

I like COD more, I find it's usually got a better story line.  Of course, I haven't played the newest Halo, so my input may be out of date.
