I believe I rather like RPGs.
Ask me three years ago and I probably would have said D&D only, but that was before my husband wanted to run a Shadowrun game, one group I was in experiment with Savage Worlds (both fantasy and Necessary Evils [supervillains]) and Dresden Files. Then Numenera came along earlier this year, and it was exactly the sort of RPG I want to GM (the style of the game encourages a GMing style identical the way I usually play, which mechanics to support).
Having now experienced other RPGs, I can more easily separate the RPG experience from D&D, which was my first and only formal foray into the genre for the better part of 12 years.
Now, when contemplating the next campaign after the 3.5 D&D one I'm running now, I want to branch out a little more. The only constraint is the pocketbooks of my players. Everyone prefers to have their own copies of the books so we don't keep having to steal it from each other when we're looking up information, and out of the six in my group, three are under tight budget restraints. It's a wee bit of a pickle for trying new things.
