Should I buy cod4 or mw2?

cod4 is so much beter than mw2 however if you want the latest get black ops or wait for mw3

It really depends on what your looking for. If it's multiplayer, I suggest mw2 (I don't think there are many people playing cod4 anymore). Actually, I would just recommend mw2 overall. The story is cool and spec ops is amazingly fun!! I think they are both very cheap and you might be able to buy them both as a bundle at gamestop. As for another game selection, I suggest Fallout 3 or Fallout New Vegas. I know it's not a fps, but the story is cool and why not try something different for a change? And of course, you can always just buy black ops, which i strongly suggest NOT to do.

Neither of them, buy bfbc II instead, no blackops.

Or wait for MW3 or BF3 to come out, cod4 is dead at xbox and ps3 and mw2 is full of noobtubers etc.

I'd recommend at this moment to buy bad company 2 if already played bad company 1

Wow don't get the two, get murderer's Creed, murderer's Creed 2 and murderer's Creed Brotherhood. those 3 video games are extra helpful than each and each call of accountability made, no hackers and months of relaxing plus murderer's Creed Revelations is popping out on November fifteenth.

Get COD4. It's so much better than MW2.

Don't get any, get Halo instead trust me you'll have more fun. And if you have that get Red Dead Redemption and if you have that get portal 2, use CoD as a last resort

Modern Warfare 2. :). No being biased or anything. there are gameplay flaws in the first one.
