I'll happily agree that Painkiller has some more variation then SS, but on the whole it's much more focused with wave-based arenas. This isn't a knock against Painkiller at all, it's a favorite of mine - yet it's still a bit inaccurate to regard it as classical level design.

Yeah, you're right. I went and watched the entire video and while they hide it well by having really big arenas, it's still just kill rooms.
