Savage Worlds is the non-d20 game in print that I would most like to try for fantasy. We had a great Tour of Darkness game with it in 2005-06, and I would like to run a Savage Keep on the Borderlands.
Warhammer Fantasy Roleplay (WFRP) was fun for about 3 months last year, but I doubt it will come back. I ran the very cool module Karak Azgal, but it was the kill-loot-rinse-repeat cycle. I never really mastered the rules. I just knew enough to get by. Needless to say, the players knew even less. I did change combat to make the mooks zero wounds and immediately subject to critical hits both to make the heroes more powerful and to make combats faster. They were still in plenty of danger and the combats had a lot of time-consuming dice rolling. I was trying to make it feel a bit more like Savage Worlds, but it felt more like D&D; no surprise in retrospect but ironic nonetheless. I would not do it differently in that respect, but it would probably still be on the table if it had been converted to Savage Worlds or even D&D--although the work of conversion is the reason I didn't do it.
Most ironically, our group is back to playing d20 this year and D&D this month. It's been fun, especially having been away from it for a while. I'll probbaly try to reprise some old games, too. But, this is off topic.
