As with when Portal 2 shipped the in game level editor, expect that I will be sharing a few Doom maps. What do you think of this new feature? Will you be creating any Doom maps?

I'm an Engineer and built the video game community Cheerful Ghost and text based mini-MMO Tale of the White Wyvern.
I would imagine I'd be creating more maps than actually playing the game if I were to buy it :)
This looks like a much easier way to make maps than other games I've tried that with. Looks fun!
