yes there is much more to do than halo 3
It depends on what you like the most. I personally like Gundam more than Halo
Halo Reach has been the best seller but now MW3 is now popular than Halo Reach
Call of duty is more realistic than halo and contains more blood. Call of duty also allows you to knife so in many ways halo is more appropriate but it doesn't necessarily mean its more fun.
Codmw2 was probably bought more than halo reach because halo r is newer. Though I am a halo reach fan.
No
Get more than 1000 gamerscore AND have more than 50 achievments.
Halo 3 is more popular then any Call Of Duty In fact, Halo 3 is the best selling FPS of all-time :\

Yes I believe Halo 1 is harder than Halo 3 on easy. In Halo 1 you take significantly more damage in Halo 1 from each shot.
Looking at the facts Halo 3 was more anticipated than ODST, the sales of Halo 3 were higher, and 3/5 people said Halo 3 was better
No
