well maybe two with Crackdown on the same day. Not really looking forward to Spore, maybe I'll get amped up fory Cryiss once I get som DX10 gear.
Half Life 2: Orange Box? It will be fun to play through HL2, Ep1, and Ep 2 all at one time with retouched graphics, portal, TF2 and acheivements on tthe 360.
Spore and C&C 3 have my attention. Unfortunately my 360 and it's upcoming releases have more of a pull.
Edit: OOO OOO! The HL1 black mesa mod for HL2, looks schweet.
