Okay, if I have to explain the joke(s), I guess I will..
Mohawk & Headphone Jack is a legendarily bad SNES platformer by TH・Q/Black Pearl. Funny trivia is that one of the EGM staffers, Martin Alessi, contributed to the game, as EGM's offices were in the same building as the developers'. Anyway, it attempts to be a mode-7 showcase, but it's shit anyway.
Xardion is an uninspiring run-of-the-mill (crap-ish) robot platformer, but it's still 21 notches above Bubsy.
