There are lots of alternative engines for the games as well. I have to re-research them every time I get an urge to play, so I, too, would be interested in anyone with an opinion one way or another to chime in with their preferred approach.

For ultra purity, there's basically only Chocolate Doom (or DOSbox and the original game). For modern features (but losing the Doom "feel"), (G)Zdoom or Doomsday; for stuff in the middle, Doomretro, Crispy Doom, Prboom+, Eternity.

I'd say Crispy Doom (or Doomretro on Windows) are good balances.

Excellent, thanks a bunch!
