lorddillon, welcome to the show and to the forums. Sorry about not welcoming you sooner; but with a new job and Origins in the fix things can get a little crazy. But better late then never right?
Looking at your list of games I couldn't help but smile to see Teenage Mutant Ninja Turtles on there. Big fan of TMNT, not so much the RPG but maybe I need to give it a second look now that I am older.
Glad to hear that the show's APs have exposed you to some new stuff and even inspired you to give them a try. Always awesome to hear that. A major point to all of this is to get people excited about GMing, gaming, and learning more about both. Trying new things is one of the best ways to do that. Score one for the good guys.
Can't speak much to 4th edition. I am one of the old guard that hasn't switched over. In fact in saddens me a little. D&D has been such a big part of my life, played since I was 9, that stepping away from it is weird. But to be honest it doesn't feel like D&D to me anymore and it didn't jell with me. But I am glad that you are enjoying it.
Anyways thanks again for finding our little show and participating here on the forums. Looking forward to your input.
