Ditto - I better bring out the Pokeballs and pack my bag. I'd go catching Pokemon with Trainer Tenryuu any day. (Too bad Pokemon Go has limited customisation abilities...)
I'm pretty sure there's a KantaiMon rom lying around somewhere, just gotta find it.
Only issue is those hacks dont replace the monsters audio, I remember when I was playing Touhoumon that Reimu sounded like a bulbasaur. If they changed the audio to say Kongou's voice clip when you send her out for example, that would be better.
