I was glad to hear that also BRP players have found my creature generator useful. Originally meant as a tool for creating mythos creatures for Call of Cthulhu, I have now added some fantasy and science fiction creatures along with some animals in to the mix. Check it out:
If you have some stats you’d like included drop me a line or two and I’ll see what I can do.
A while back I made this NPC generator for a Finnish role playing game called Praedor. I received pretty good feedback for it, so I decided to modify the same tool to generate random monsters for Call of Cthulhu as well. I thus present to you, the Call of Cthulhu Creature Generator:
It’s pretty cool. And it’s pretty simple. Choose the monster you want, click “generate” and it’ll roll out the creatures for you. You can also set the desired level in order to create above or below average creatures. It’s a shame I wasn’t the first the blog about it, Cthulhu.de beat me 
There’s some discussion about this tool also on the awesome yog-sothoth forum. Leave a comment below for any feedback or suggestions. I’m always open to new ideas, especially if they are easy to implement
