Here's a brief list of what's being released on PC this week in the UK. As for a highlights? TOCA Race Driver 3 is an obvious one and Crashday looks fun. Gal Civ II should also keep strategy nuts occupied for a while.

Galactic Civilizations II: Dread Lords
Crashday
EverQuest II: Kingdom of Sky
Hammer & Sickle
Keepsake
Loco Mania
Narc
Onimusha 3: Demon Siege
Panzer Elite Action
TOCA Race Driver 3

Can't say I know an awful lot about the rest.
