Hexxen is pretty amazing. The rules are extremely simple, but maintain enough complexity to still be fun and it knows what it wants to be and focuses on its core goals. Investigation is fun and engaging, combat is fast and dangerous, but not necessarily deadly and there are numerous interesting character classes that you can combine to build exactly the witch hunter you want.

Other than that, I'm working on my own system with a combat experience similar to DnD, but the social complexity and character customisability of The Dark Eye.
