Uhm... I hope you mean their commentary, not the games. Adventure is decent if you play the updating, ie. gamecube version, but the other two are horrible horrible games. Their commentary on it was funny because the games were bad so they could play off of that. With Black Knight the game isn't actually bad, so they have nothing to talk about other than how terrible Arin is at the easiest Sonic game outside of the racing games ever. It's not entertaining.
I am referring to the commentary. Adventure is just fun in general, albeit glitchy (I played the DX Director's Cut on GC), but the other two were so bad and the commentaries were extremely funny.
