James and Klaxon are going great guns on Look, Up in the Sky! - the supers game using the StarCluster system. They pulled in the Cluster Generation tool from IHW:SC and used it as a template for a City Generation tool. They've also adapted the Association rules from OHMAS to use for creating the Super Team's assets. LUitS! is very much a team oriented game. PCs are part of a team like the Avengers or Fantastic 4 rather than lone supers like Batman or Flash. They are looking at being able to run anywhere from Pulp level to ultra-powerful Supers level.
They are adapting the Paths of Power from Blood Games to supers play, using the Paths as keys to base your character around. For example "Brick" would be a Path, able to choose among Brick-type powers and skills. Skills have been greatly condensed - there are something like 20-24 skills which encompass everything - because of the preponderance of Powers. They are using the StarPool mechanic as the base for their system, though it should be easily changed to any of the available mechanics.
I'm really looking forward to how this all comes out! :D
