My oldest son, in addition to playing a 3.x game with me and my younger son, plays "D&D" every Saturday for about 3 hours.
He is playing with my sometimes DM, sometimes player, Greg, his sons and a couple of other kids all between the ages of 11 and 12.
You can read about those games on Greg's blog: http://rhoninsramblings.blogspot.com/
They are playing ACKS right now and my son loves it. He likes that it is so old school and there are not a bunch of rules he needs to play. But they are going to do B1 and B2 and maybe even X1.
How much better can that be really?
Anyway, go to Greg's blog and you can be jealous too.
