Hi. I am printz. I like Eternity and such advanced ports. I also like Heretic and Hexen a lot but I don't dislike Doom. When it comes to Doom PWADs, I really like those that delve into fantasy themes (usually deep hell with all its weirdness). Custom monsters rock.
I am not very fond of mere gameplay mods because I can make them as well for myself (sans the "new graphics" part). I'm slightly disappointed that most ZDoom mods in progress these days do little more than 'mutate' the gameplay. Where's the ZDoom megawad?
