Agreed that the Sakkra variant I proposed would be too extreme (at least on Impossible). I think a "no bombs on ships" variant would be playable though (those who know the game better than I do can decide if it would be too much for an Impossible Darlok game; we could always go with the Sakkra or the Alkari or something instead). Unlike the "Belligerent Bears with Beams" OSG, we'd at least be allowed to research missiles for defense, and build missile boats to burn bases and harrass enemy fleets.
All that said: In spite of the fun I'm having continuing to dream up variants, as I look over this thread, it looks like there's a kind of consensus for Vanilla Mrrshans or Hostiles-Only 'Coids. I kind of like the idea of following up our last SG by teaching our "ally" Shandra how a real kitty emperor does things, so:
Assuming we play Vanilla Mrrshans, what galaxy size would you prefer? (Or, in light of recent discussion, would you prefer another variant?) I'll cast a "soft" vote for Medium size, but would be happy with anything - even Huge(!), as Alan suggested, if it's preferred by the majority. (@Alan: Did you want to play in such a game, or were you just offering the idea to the team?)
Those who'd like to (and have time to) play another OSG, please weigh in!
