I'm interested in Commander Keen and Wolfenstein 3D, but I like other games as well like Doom. I'm planning my first Wolf3D mod, which is Crime Fighting 3D. It'll be based on Spear of Destiny.
Actually, I'm mainly a Commander Keen modder since 2008/2009. I've made Keen 1,2,3,4, Dreams and 6 mod(s). (I'm the creator of the first true Keen Dreams mod!)
Later, I'll plan Keen 3D as a Wolf3d mod.
Well, that's all shortly.
