What games should I get for my 2 year old macbook ?

I have an about 2 year old Macbook (intel) With these specs:
Core 2 Duo 2.4 Ghz
and 2 gigs of ram.
The Video card is an integrated 9500 something IIRC..

I would like to get a few new games soon, and I would prefer that they run on my machine :p
Since I have boot camp installed, both win and OSX games are good.

The games I have spent most time with uptil now is strategy games, like Civ 1 & 2, Alpha Centauri, Caesar III.

Most action games I play on either the 360 or PS3.

Lurve for good suggestions :p
