Pacific time here.
My experience is pretty much limited to D&D. I've played a little of 3.5, but most of my experience is with 4e. I really loved the tactical options, but at the same time, feel like combat overshadowed everything else. I've DMed for it as well, running mostly premade adventures.
Now that 5e is out, I'm excited all over again. I have the PHB and I've DMed the starter set adventure "The Lost Mine of Phandelver". I'm interested in playing as a player or DM.
I'm open to trying other systems too, but I probably wont be buying any expensive books for non-D&D products unless it's truly special.
