Underrated game. Good suggestion here, especially if you like quirky Earthbound inspired games.
I'll add SMT and Persona, they aren't super replayable but they have a ton of monsters and party combination like Pokemon. P4 is my personal favorite though Demikids is a clear Pokemon-clone so that might be worth checking out though I found it too simple compared to the main entries.
There is an Animorphs gbc game I loved as a kid that was a clear Pokemon clone but I'm sure it didn't age well
