Hanamikoji could be a good option.

True! Curious to hear more about where OP will be finding folks to play with them.

Radlands is great, but I question whether a random person on the street will be able to learn it and have a shot at winning?

Glad to see Innovation getting so much love after being on SUSD. It's really a great game.

I've also enjoyed exploring Mottainai after everything in the rules finally clicked.
