Kane & Lynch: Dead Men, Xbox 360 - £4.99 delivered
Good old games have got a fairly promotion on at the minute. All these bundles for $9.98 each:
Fallout & Fallout 2
Freespace, Expansion & Freespace 2
Descent, Descent 2, Descent 3 + Expansion
MDK & MDK 2
Stonekeep & Lionheart
They all come with Sountracks and other bonus material too. Grab them here.
You can also get the sublime Beneath a Steal Sky, and Lure of the Temptress (which I haven't played) for free, here. They are both freeware anyway, but GOG will sort of the XP/Vista compatibility for you, which is nice and convenient.
Thanks to Matthew for the tip off.

I played the demo of this just before my red ringing. Not too shabby at all.
