Cassette Beasts is an indie open-world RPG, where characters can transform into unique monsters using cassette tapes. While on paper the concept sounds a little weird, the trailer will absolutely sell it for you.

The Pokemon-esque RPG also has a fusion feature, where you can fuse any two monsters to come up with unique, more powerful forms. While never in the actual Pokemon canon (aside from one instance in Sun & Moon), this concept went viral thanks to the Pokemon Fusion website, which automatically creates a new Pokemon from a combination of two existing ones.

With monsters appearing as transformations rather than individual creatures, the player's relationships with different characters will also play a role in their combat success.
