D Cups Full of Justice
This character generator is extremely in-depth, but doesn’t have a fancy GUI. It has an insane amount of options built into it, however, and is useful if you’re trying to build a creature or NPC using any of the expanded races and want to save all the time cross-checking penalties, bonuses, and such.
I have been using this to quickly and easily roll up major NPC’s with stats. The interface is nice, but may seem overwhelming at first. Allows you to export very nice looking .pdf files of the character sheets, which is just lovely.
Extraordinarily useful for quickly generating ideas for towns, worlds, NPC’s, adventures, names. Really helps spur and prompt ideas, and I highly recommend this site. (This site also can easily and quickly generate maps.)
