Mork Borg is amazing if you haven't tried it. It can be brutally unforgiving, but it is meant to be a grimdark and on par with Zweihander. The art and lore is fantastic, I haven't seen anything similar to it before in that respect.

Dragonbane (published by the same group as Mork Borg) has a 40th anniversary updated rules edition releasing this summer that looks amazing too. I funded it on Kickstarter and it looks like it will be a wonderful revamp of a classic 80s rpg.
