Speaking of doom wads, i gave
Heretic a try.
It has pretty colours, i like pretty colours. Soundtrack is also nice.
I can't help but feel like i am playing an inferior version of Doom though, not to say that this is a bad game - just not as good as Doom. Maybe it's because of difficulty? Didn't want to touch anything above medium because i heard something about enemies becoming HP sponges, but things are so easy so far the tome of power is something i use to reduce tedium instead of being my "Oh shit!" button.
