The session is underway as I type this (we play online). I'm doing my best, but they're damned clever little players! As of right now they've come up with some fairly brilliant strategies involving long-range teleportation, local stars and black holes, and Cosmic Consciousness.Sounds a bit like Dragonball Z, in that really bad things can happen, but they just get undone with the titular dragonballs (ie. Seventh Sense).
I still think actions should be grounded in consequence though. But I guess at the levels you are playing at why shouldn't the game have come full circle.
EDIT: For those curious how it turned out, if any of you can think up a strategy for evading: (a) first teleporting in thousands of Interdictor devices designed to sabotage any attempt at warp or hyperspace travel, so FTL transport is no longer possible, and then (b) teleporting in a stellar black hole DIRECTLY ON TOP of the large nanite cloud in the VERY NEXT ROUND... I'd like to hear it! Kudos to my players for coming up with this short-circuit to my plans. I'm off to calculate a massive XP award here.
