re : new Gaim shipset
As I'm laying the Gaim in the PBW I just had have a look. Ohh, pretty.
re : RCEs in PBW
No idea on what effect it has during a players turn. I know in single player that a RCE during the AI processing kills the game. Tip : never let the combined ship speed from your engines (before the divisor from ship size, not counting bonus moves) pass 255. Simple Version of this rule - keep your engine count to at most 30 and you should be safe no matter what engines you fit. It's a limitation of the game engine.
