Just wanted to add my two cents on Coded Arms:
Got this game yesterday along with Panic Bomber (which is a fun puzzle game like the Neo-Geo and Virtual Boy versions before it, but what is with the GBA-quality music? I expect a lot more from PSP games in that area), and was surprised to find that the entire game runs in 100% English.
It takes a little bit of adjustment for the controls (I used the Turok style setting, with the face buttons for movement and the nub for look), but so far I'm finding Coded Arms to be a pretty fun game considering that Japan is not exactly known for making great FPS titles. The frame rate could be a little smoother, but it seems to stay solid and the visuals look very nice; it's not too terribly challenging as of yet but I'm still getting started. There's a nice variety of weapons and you can also pick up armor upgrades.
For a game that was supposed to suck (although the [worthless imo] Famitsu scores were 8, 8, 7, 7 which isn't bad for the genre), I'm pleasantly surprised.
