So @brad dropped a stealth wiki bomb on the latest podcast that got my juices flowing. It's quite possible he was referring to Battlefield 4's destructible environment thing, but I immediately thought of other games and ran here.
After due diligence of checking the COD:Ghosts and Split/Second pages, there's no existing concept that seems to describe "static map alterations during gameplay by player interaction", whereby a switch is flipped and the entire map is now in state B instead of state A. As much as I'd love to have "Levelution" on my list of created pages, I don't actually think that's what a generic concept should be called, even if it's not trademarked by DICE. It's a fine alias, but it's no Abilitease. :p
I'm also not sure how to describe it in such a way that it doesn't apply to all games everywhere. Probably it doesn't have a page already for exactly this issue. Think about stepping on a platform in FF6 to create a doorway through a wall. That's a minefield of a page... anyone have better ideas about what the distinction is, if any?
