I've teased my game with my semi-regular gaming group, and got some interest. I will need to do some rules revising/fleshing out before I'll get a chance to run Appliance Adventures.
My regular Friday night group agreed to test it for me, and already I have some suggestions for tweaking the game mechanics (several people asked for more Tricks, and one came up with the idea of scaling Tricks like skill levels). Overall it worked pretty well, but I found that the current rules for combat damage leave open the possibility of one-hit kills, which aren't fun when they target PCs. Final verdict: the game works OK as is, but there is definitely room for improvement.
It occurs to me that this is only the second of my five 24-hour rpgs that has gotten a playtest (the other being Immaculate); I need to draft my friends for this stuff more often.
I am now three sessions into a playtest of Apotheosis Blues, and the players have already shown me some changes that needed to be made (other than finishing the bloody thing, that is). I added all kinds of stuff for item creation, and I now have the beginnings of a bestiary. The new version has already been submitted for inclusion on the list.
