I like C&C alot, but I still will and have played D&D. Note the key word...play. I will not run D&D at this point in my life. Won't go into why, because I'm not trying to start another C&C vs. D&D war. I will say in my group, all of my players both run and play C&C...with D&D I'm the only one who run's it, though they'll play. I also find when introducing new people into the hobby C&C really does work better, in my experiences, than D&D. So yeah I'll play both...but run C&C.
I accidentally chose the 3rd option because it was mistyped. Otherwise, I would have chosen the sixth option. I have the C&C books, and was curious about it, but given my recent exposure to a few bad apples, I am no longer curious. Frankly, if I want a rules light version of 3E, I'll write it myself from the SRD, because what has been done so far just doesn't cut it for me.
