I give my current campaign an 8 rating. It's a good time, but the bloom is coming off the rose. I incorporated elements (classes) from three other d20 games so that it wouldn't feel like plain vanilla D&D. I also added in aasimar paladins to encourage heroic PCs. It has worked well and has been better received by my players than I expected this cross-genre game would be. But now I feel like I've done it, so I'm just playing out the next 10 modules in the Shackled City adventure path. I'm already finding the villains have a good deal of complexity as foes in combat, and I think it will only get worse as the game gets higher & higher in level. Plus, the players took about 4 months to finish the 1st adventure. I'm hoping to get the second (current) done in half that time. I would prefer it if they did about 1 a month. I'm doing what I can to speed play without lessening the experience, and I definitely feel like this game is the best refinement of my DMing & gamecraft.
Now, the 1e game I've played for the last 2 weeks is probably at a 4--just enough to get me to come back this week. Luckily, I think it will go only about 6 sessions maximum total before the DM ships out of town.
I'd have to give the single-session all-jedi Star Wars game a 10 so far. I can't wait to play it again. Last time, all we did was negotiate; and I loved it. And I will unabashedly call myself a power gamer with some min/maxing, munchkining, rules-lawyering tendencies. Perhaps I'm finally evolving as a role-player. (The minis game can't be hurting either. It's great, but I won't rate it against any RPGs.)
Overall, I've got a lot of good gaming going; and I'm happy for it!
