Gaming Ballistic has picked up Tower of the Moon and converted it to the recent The Fantasy Trip system. It is whole new layout and additional content and maps. They did a bang-up job and I recommend it if you are interested in that game system.
They are also helping to publish a new edition of the OSR version that Night Owl Workshop made a while back. It is an updated version with a few new bits and maps. The hardcopy version is quite good, much better than print on demand.
Head on over to the crowdfunding page to check it out: https://gamingballistic.com/tower-of-the-moon/
