Cassette Beasts was an absolutely beautiful game with a banger soundtrack and managed to recapture the joy of playing Pokémon from when I was a kid, something which even Pokémon games can't seem to do now.
I played Pseudoregalia and beat it in a couple hours and thought it was kinda meh. Then the next day I was kinda bored so I played it again start to finish. And then I played it like four more times that week. It very quickly became one of my favorite games of all time; not perfect on a first playthrough but one of the best games ever to replay.
