Walk inside Big Gay Al
Maybe Stick of Truthis more true to the series’ 2D look, but this 3D, virtual recreation of the town of South Park is a pretty cool alternative. Characters keep their flat look and always orient themselves towards you while everything else is navigable in three dimensions, yet still looks sort of 2D and construction paper like. Not as wild as, say, that new Guilty Gear, but I like it for the same reasons.
Stick (of truth) around until the end for a nice visit to hell.
