I recently acquired a PS3 and I need a bunch of cool mecha games. Japan-only titles are fine too, but I can't read so it needs to be simple.
Dynasty Warriors Gundam 2 & Reborn (latter is digital-only in the US)
Armored Core 4/For Answer and VD
Zone of the Enders HD Collection (as long as the performance patch is still automatically sent)
Metal Gear Rising: Revengeance
Gundam Breaker 2
If you're already into it maybe SRW 2nd OG but that's sliiiightly complicated in the moonspeak.
Whatever the latest GvG is for PS3 I can never keep the names straight
Never get ACE R
