*Burning Wheel -- I've owned Burning Wheel for three or four years now, and would love to try it . . . . but I know for a fact that my group would never, EVER go for it. I'm pretty sure this one will be relegated to the long list of "purchased, never played".
*Night's Black Agents -- This is one that we'll get around to at some point, if I pitch it to the group properly.
*Genesys -- This one's more likely than not, at some point. I like the concept and "feel" of the rules, but am leery of springing something new on the group after we started Dungeon World but then aborted it a few months ago. I'll give this one some time to "simmer."
The big thing for our group now is that we all have a lot of experience with Savage Worlds, and it's so easy to switch genres/settings with SW, that sometimes it almost seems more work than it's worth to try a new system. The actual in-play experience has to have enough of a twist, or unique hook built into the rules to make it worth it.
The other interesting thing for me is, there's not a single d20-based system anywhere on the radar. Pathfinder/PF2 Playtest/D&D 5e simply don't interest me in the least. I've had a copy of Fantasy Craft on my shelf for six or seven years now, but once again have realized that it's just one of those games I'm never actually going to play. If I wanted to go super-old-school, the D&D Rules Cyclopedia or Adventurer/Conqueror/King sound interesting, but Savage Worlds is already fantastic at emulating low-level BECMI/Basic-slash-Expert D&D style play. I've said it before on these forums that Savage Worlds was the first system that actually delivered on the experience I was promised in the pages of the 1983 Red Box.
Plus, truthfully, everything in the d20 category feels like a step backwards in game mechanics now. Once you break free from class/level based systems, going back to one feels like an unnecessary compromise.
Oddly enough---and I'd NEVER in a million years have thought I'd say this---the one D&D game that I might actually consider trying would be 4e, because it would at least be a different kind of D&D game from all the others. My tastes have changed enough now that "bog standard" D&D-style systems just don't hold much appeal anymore.
Edit: Just thought of one more --- Novus. I picked up the free beta on DriveThruRPG a while back. It seems like an interesting mash of D&D concepts with a unique dice component. Not sure the dice component in and of itself makes it worth it alone to try, but it's at least on my radar.
