A good story, fun characters, an interesting world with facisnating world building. A fantastic battle system. It's a shame Cassette Beasts didn't get as much hype as Palworld is getting.
Not to shit on Palworld or anything, I just feel that half the attention it's getting is a little ... unearned...
I stumbled across it a few months ago and really liked it. The story was compelling and exactly the length it needed to be. Short enough I never got bored but long enough I got explore everything I wanted too.
