Vanilla Randomizers?

I like the concept of plugins that randomize monster placement, but the ones I've found so far (like the ScoreDoom add-on) add a crapload of monsters that, for me, feel really out of place in the game. Are there any randomizers that use only the default Doom monsters? IMO that would be an extremely cool thing to have.

Randoom. But it's for Doom 1 only. Don't use it on the entire 4-episode Doom.wad, it will crash. Instead, extract ep1-3 and ep4 respectively into two pwads, and randomize them.

The vanilla version of this one sounds a bit like what I'm after.

Think I might give it a try since I want something that will work with a larger variety of WADs.

If you want to go one step further with random levels as well, check Oblige out.
