Sonic Adventure is one of those games that gets praise just for not being a shit sonic game.
But like. It is a shit Sonic game. It was shit on the Dreamcast and it was shit with every re-release.
It is overrated though, that much is fully true.
Also the console exclusive characters were genius.
Except for the Xbox people stuck with Spawn. Heihachi was so fitting it's a wonder they didn't bring him back instead of fuckin Star Wars and Assassin's Creed for 4 and 5.
