>>13407588The Gundam Battle/Gundam Assault games for psp are pretty good. You can spend money to upgrade stats, weapon damages, weapon ranges, payload, etc however you want but you can't change the loadout. There are a metric fuckton of mobile suits in the game, though, so you don't really need a custom because pretty much every model ever is already in the game from Zudah to Freedom.
Actually SEED and 00 season 1 mechs are only in Gundam Assault Survive. Gundam Battle Universe is UC-only. GBU has slightly better textures and some neat atmospheric effects like rain, fog, and sandstorms. GAS has the SEED and 00 eras and the ability to have every mission from every era on one save file (GBU makes you pick a side when you start each era). Also several pilots got cut form GAS, like South Burning, Elle Vianno, and a bunch of characters from other Gundam video games like Zeonic Front and stuff, and while GBU unlocks MS by completeing special objectives or capturing MS during missions, GAS makes you buy plans to develop MS in order to unlock them and then buy the MS you've unlocked. Other than that they play pretty much the same.
