What bothers me more is that I've played all of those (and much, much more) aside from Crucified Dreams (because I don't care for online DM in Doom) and Doom Core (because I only started playing yesterday).

Like some others here, the list of praised wads that I haven't yet played is pretty extensive, and it keeps getting longer, as more projects are finished before I play through the earlier stuff. Just off the top of my head, I've never played Serenity, Hell Revealed 2, Action Doom 2, Harmony, Speed of Doom, Alien Vendetta, Crucified Dreams, Memento Mori, Memento Mori 2, Icarus, Scythe, Doom Core, Null Space, Unloved, Kama Sutra, Congestion 1024, Deus Vult, Plutonia 2, or Whispers of Satan.[/list]
I'm also a major league completionist, and will very rarely just give up on a .WAD and not play it ever again. If I'm getting bored or frustrated I'll just save, quit and come back to it some other time.
As for the plasma gun... the sound annoys me, so I'll very rarely use it, and instead just keep buning through the virtually unlimited shells the average mapset supplies me with, or pull out the BFG or RL for crowd control.
