Rating : - One of the most replayable games ever.
PROS:
- Best graphics you can get on the PS3
- Addictive online gameplay will keep you hooked for YEARS.

CONS:
- No dualshock 3 support.
- story mode is only 5-6 hours depending on how good you are.
- Even though the online is the best part of CoD4, 50% of the time your game will be abruplty ended by the host or a connection failure. It can get pretty annoying.

So pretty much the online is what you'll be doing 99% of the time even though it has it's flaws. If you don't have a high speed connection I recommend you rent it.
