Just wanted to provide a link to Villainy Unpublished, my dedicated SRPG resource blog. It’s been up and down for a few months while I argued with the formatting but I think it’s stable and serviceable at this point. There are a few general musings posts but most of the current content are homebrew villains from various games, along with associated minions, lieutenants and environments. I strongly recommend using the labels on each post to navigate around, as there are about 50 individual posts at the moment.
My current absurd project (which will probably never actually be finished) is to do one of every possible villain approach-archetype combination, mostly as a creative exercise. With today’s posts I’m about a third of the way done; only about 164 to go if I’ve counted correctly.
There will also be some hero writeups, rules variants and other maunderings as the mood takes me, but they’re probably less useful to other people than more bad guys. One of these days I’ll get the villain index updated properly as well.
Feel free to comment on posts over there, although I do have moderation turned on so it may take a while to show up.
