Currently I'm part of three gaming groups:
1. Participating in a Pathfinder campaign. I dunno, it's a fun game with a good DM, but darn if the seams of the system showing. It's a low-magic setting, so we're 7th level without a single magic item to our name, and it's clearly causing some balance issues. Some tough encounters we've curb-stomped, but we just had to flee in terror from a Stone Golem, given its impenetrable DR. Is there any equivalent to 4e's Inherent bonus system for Pathfinder?
2. My home 4e group wrapped playing through Revenge of the Giants. It was a good battle fest. I started running Fate Core and 13th Age for then, and it's throwing some of players for a loop. They're too used to 4e's more mechanical character generation. The freeform backgrounds and One Unique Thing in 13th Age shut down a few players, and aspect generation in Fate Core was also a real chore. I like both systems ... but I feel like I need a different group to play them.
3. The group I played DnD Encounters with is on a hiatus with the DM in university. No one wanted to shell out for the latest season, so the last season DM offered to just continue the last season with his own stuff. That means we're still playing Next with the July playtest packet.
Ultimately ... despite all the gaming, I'm a little frustrated. Neither 4e, Next or Pathfinder are really doing it for me system-wise. I like 4e a lot, but I want to try hacking it, redoing feats and magic items into something less bloated and treadmill-y. Next just doesn't feel ready yet. Pathfinder is still 3.5 when all's said and done, so I'm seeing the flaws of the system in technicolor.
So, I'll play any of those systems, but haven't felt the desire to DM them. And despite my enthusiasm for Fate and 13th Age, they haven't really caught on with my home group, which is vexing me.
