One of the best Gundam games yet!

IF you can get your hands on a copy of this I recommend it! You really don't need to know Japanese to play this one (I don't :P ).

Ironically I rate this game 10x better than Crossfire for PS3. Its fairly long in duration, especially for a PSP title, and has excellent replay value.
Gameplay is solid, highly reminiscent of older PS2 games like DX and Lost War Chronicles. Now instead of changing the weapon on your suit, you upgrade your suit with XP points accumulated from battle. There is a good amount of suits, some with up to 4 different types of weapons/ attacks.
Its cool be in control of basically all new mobile suits as well. Im not a fan of the SeeD series, but this game is downright badass in suit selection/ weaponry.

Some could argue that the stages get monotonous, but like any Gundam game, we do end up cycling through the maps. However with the expansive amount of suits to take out, stage repetition is hardly noticed.

This one might be under the radar but if you come across it, scoop it up...
