Macbook pro gaming

I Recently bought my first mac which is a macbook pro 13inch intel i5.

I love the Apple OS and realise how bad windows is in comparison but i prefer having games on my laptop than a console or pc since i move around alot.

I tried using bootcamp for some of my old games but they lag a little and its annoying.

So basically my question is what great games are there for mac ? (besides l4d + half-life since i already know there awesome)

I play COD modern warfare on mine and it rocks.

I have an older MBP and dedicated 128mb Video and I play Starcraft2 it works fine, without diminishing gameplay, as for your machine, some games could be hard to play because they are resource hungry and scream for a large VRAM...but you wlll be able to play many games....

I love playing Red Alert 3 on mine
