Soon, I will be starting a new AD&D 2nd Edition Dark Sun game. The last characters died in an unfortunate accident, when they started a riot in Raam and attacked Abalach-Re. There will be 4 players, with a NPC to round out the group.
I use the split stats from Skills and Powers, as well as the proficiency system from that book. I use spell points from Spells and Magic and am toying with the idea of making the priests in the group channelers. I use various combat techniques from Combat and Tactics. I used the phase initiative system in my last game, but I think I will be doing away with it this time.
