So, I’m a big JPRG fan and just playing through Mother 3. I love Mother 2 (aka Earthbound) as well. I love the music, quirkiness, style, pacing, simple yet rewarding tactics in boss battles.
So, I would appreciate any game recommendations you have for a similar game or game series.
If it helps, my other favorite JRPGs are: Chrono Trigger, Final Fantasy 6, 9, and 10.
This is going to be a bit of a grating answer, but, aside from Undertale which is a partial homage/subversion, the Mother series is very unique (on purpose).
You might like Live a Live if you want a JRPG. Otherwise, The World ends With You is a gamr that overlays a fantasy world over a seemingly ‘normal’ setting with a very unique art style. There are versions for different platforms but if you decide to play it you absolutely need to have a (3)DS
I tried Live a Live many years ago but barely. I think that’s a good suggestion.
