Best games to buy second hand?

[Paul -C-]

I've skipped the last few years of PC gaming, so I wanted to go back and play any really good games I've missed.

I've ordered Farcry and Chronicles of Riddick and I've also got COD2, which I really enjoyed.

So what would you recomend I buy?

System is Athlon 4400 @ 2.4, 2 gigs ram and a 1900xt.

Cheers!

Thanks guys!

I've now got a few games on their way to me:

Call of Duty & United Offensive Expansion Pack
Mafia
FarCry (already downloaded the 64bit textures!)
Chronicles Of Riddick - Escape Butcher Bay

Should keep me busy for a while!
