On one hand I gotta say I'm impressed by Romero's dedication to making maps for Doom 1. The first Doom has a very particular balance to its weapons and monsters and Romero's very good at playing with that balance and making cool levels with it.

On the other hand: holy shit dude we gotta get John on Doom 2 so he can start putting Hell Knights in levels as "big imps" instead of Hell Barons. You fight SO many hell barons in this thing.
