Gaming

Hi guys, I am new to the world of Apple.

I have just bought an Imac 2007 model.
Specs are:
1.8ghz powerpc G5
memory 768 mb ddr
I am currently running Tiger

I understand that these computers are not designed for running games but what would you suggest that might work?

Not too bothered about running 'older' games, wouldn't mind playing some nice platformers/shooters

Thanks for reading.

The original Call Of Duty should work fine, also Unreal Tournament 2004. Warcraft 3, and Starcraft will work. Plus the always awesome Age of Empires 2.

Thanks for the reply. Any good 'cute' 2d platformers out there? Frogotto style? I love 'old-skool'
