If you do have some problems hindering your content march, Nomad, then reveal how you've been porting them to as many porting-rigging-capable individuals as possible, and have them continue in your absence. ...We also need Ur-Didact and his Promethean Knights (someone should be working on it by now)...

That's a mighty tall order there, but I'll see what I can do. I don't know when though, because I'm having problems that I'll type up in my profile.

RandomNomad, I commend you for doing something nearly nobody is doing.
Now, a small list of big things.
Death Knights (of both genders, of -MOST- of the races, you don't need to do all of them).
Crypt Lords (various skins and sizes).
Structures (because you could).
Elementals (you could, if you wanted to).
Ragnaros (in his newest rendition, with bodygroup for legs, with Sulfuras (Ragnaros and Sulfuras in varying sizes) ).
Felguards (various skins and sizes).
Other demons (if you wanted to).
Fel Reavers (various skins and sizes).
I could go on FOREVER.
You should look for people to assist in bringing all of these models unto Gmod.
I'd prefer if you began porting Felguards and Crypt Lords first.
Shouldn't be too difficult, overall.
You need not make playermodels.
