Fair - it’s more accurately an action RPG (or RPG + arena brawler?) - but mentioned with 3rd person shooting robots in mind.
Once OP started talking about Chibi Robo and MechAssault we’re straying away from shooters proper anyway (but this could be my own bias).
Mostly just curious on OPs take on it.
If you’re an adult Pokemon fan, these days fan-mades or rom hacks are the way to go. Nintendo/The Pokemon Company/Game Freak are pretty damn risk averse with this property, so the really cool stuff comes from fans (at least until they get the cease and desist).
