Should I buy it ?
Is it better than Resistance fall of man
And
Halo 3 ?

I believe CoD4 has possibly the best campaign mode out there. Every mission was killer. Unfortunately, there is not a CO*OP for CoD4 campaign like Halo 3. CoD4's campaign is pretty short but it is very rewarding. The graphics are well worth the 60$. I have not played Resistance Fall of Man but I did play Halo 3. Since CoD4 came out I haven't played Rainbow 6 or Halo 3. I haven't removed CoD4 from my Xbox in over a month. The Xbox Live options are not nearly robust as Halo 3 but CoD4 to me is more fun.

So far, CoD4 is the best game I have owned.

According to IGN's 2007 video game awards, COD4 was the best XBOX game of the year.

I agree COD4 is an awesome game. I think it's worth all the money.

Oh man, play COD4 for one whole day and well you'll literally cry at the end like I did :p. I played through the whole game in one whole day on my first time ever and I almost cried at the end 'cause I literally felt part of the game :D. It was a nice change from the jungle levels in Crysis, so go figure :rolleyes:

HELL YEAH! I love it. It has f*****g awesome graphics. Now I have a question. Should I get Call of Duty Modern Warfare 2?

Oh hell yea. There are some questionable players out there glitchin on line but it is still a blast. The Kill Streaks are addicting as hell. I checked my account last night and have played it for 19 Days since it came out. Kill Me.
