Reading about Gamer ADD makes me rethink my own games for the past 15 years or so.
Of course I suffer from Gamer ADD. Back in the day, we had D&D and Star Frontiers, and we just played either when someone had a dungeon or adventure ready. We had two long campaigns that lasted from late elementary school into the early years of university summer vacations. 10 years for D&D, 8 for Star Frontiers. We'd try out the occasional other RPG, usually during the summers when we had lots and lots of free time. But the only ones we stuck with were the above.
Then, after I graduated, with the Evansville group and every group I've had since, the big problem with Gamer ADD was NOT that the DM wanted to switch systems or campaigns.
The problem has been (and still is) that EVERYONE WANTS TO BE THE DM.
Too many chiefs, not enough Indians. Especially in my current board game group, there are always one or two of us dissatisfied with whatever is being played, so the usual response seems to be to offer to DM a game the way you like it as a player (which of course then makes someone else want to DM their way).
On another note, I've got the Character Creation rules for the Flying Swordsmen (Dragon Fist retro-simu-something) RPG finished. Character creation basics, classes and kits are done. Next is the martial arts maneuvers and combat section.
And this is my 100th post. Huzzah!
