Another oldie
Swordbearer
This was a fantasy game last published by
FGU around 1982 or so. A great little system (that I never got to play). It was skill-based and used a fairly unique magic system. Essentially, you collected "nodes" which were essences of various primal elements or else from living beings, stored them in crystals, and then used the nodes to power your spells, with certain types of nodes working best with certain schools of magic. This was also the first game I ever saw that dispensed entirely with currency. PCs had a Social Status rating, and it was assumed that you could afford anything rated at or below it.
Element Masters
Basically a copy of Runequest 2e with a sense of humor. I have no idea if it's still in print or not.
Jorune
This game managed to make it through three editions before going OOP. It was qute a loyal fan base, though, and there are lots of resources on the Web. Basically, it was a planet colonized by humans in the distant past, but had since devolved into a Renaissance-level society with alien races, uplfted animals, and human beings. Plagued by a convoluted rule system.
Tekumel
A number of rule systems have been paired with Tekumel, which is a very Indian-themed fantasy setting created by M.A.R. Barker. Next to Tolkien, Tekumel is probably one of the most detailed, vividly imagined settings ever created. Guardians of Order are coming out with a new Tekumel game in 2003. Awesome fan site can be found
here.
Fantasy Wargaming
Released in the early days of the hobby, this was more of a sourcebook for fantasy gaming in general, though it did contain a system aimed at being very "authentic." I haven't read my copy in years, but someone reviewed it recently at RPG.net.
