I'm anticipating Armored Core 4 for Xbox 360 and Playstation 3. So far it looks really awesome. The theme of the game is "God is Force." It looks like they are pushing the limits of the PS3 since the hardware appears to be pretty powerful for a game system. The series started in 1997 so it's approaching it 10-year anniversary. The game has evolved into something extraordinary considering how the game first started out.

Here is a list of all the Armored Core games I owned:

Playstation 1
-----------------
Armored Core
Armored Core: Project Phantasma

Playstation 2
-----------------
