Category talk:Levels with optional keys

Speedrunning antics
Such a category is an interesting idea, but where are we going to draw the line? At least E1M4: Command Control (Doom), MAP14: The Inmost Dens (Doom II) and MAP31: Pharaoh (TNT: Evilution) can be finished without any keys, so those levels have unnecessary keys as well.

This lists levels where one or more keycards or skull keys give access to optional areas? --Jartapran (talk) 12:38, 10 March 2016 (CST)
