TBH putting the pc into the fray will just murder the consoles. The PC can be upgraded with hardware whilst the consoles can't and over time it'll never match up to the pc as it has the freedom to add the latest best parts everytime. But then again, if its tolerable on the consoles and the differences minor, perhaps its not such a big loss at all... especially when it'll cost the pc users money just to have one up on a console.

Wheres bad level design? poor game concept ideas or the classic problem of slip sliding away levels? Lousy games that over use bottomless pits to kill players? Touching enemies hurts players? spikes? Poor level design where you don't know whether something is in the background or foreground and whether it could affect players?
