If I had my druthers I'd be playing nothing but Star Wars Saga Edition. So far though every Star Wars campaign I've been attached to has either sputtered out after a few sessions or failed to even start.
The D&D group I'm currently in will likely still be playing 4th Edition at the end of 2008, but whether I'll still be around for it remains to be seen. So far 4E is requiring more processing power than I'm willing to put into a game. If playing 4E doesn't get easier soon, I may drop out.
I was just wondering, now that 4E has been read by most of us and that we know more about the Pathfinder RPG, what version of D&D do you intend to be playing, say, by the end of 2008 ?
3.5 until the current campaign finishes, then likely moving on to 4E - hopefully, there will be a pretty firm set of errata from the 3 core books by that time.
