I'm really glad you are putting the effort in to play test this version of the game even though I don't think it will work. It's good to see more than armchair quarterbacking (what is the British phrase for this?) - and I put myself in that group too as unfortunately I don't get to play much.
However here's what I think is the problem with move and fire.
I could hide my ship behind an asteroid field at long range and leave it until the last ship to move. Then it comes out and fires at a ship that's already moved and fired. The next turn I win initiative. I fire that same ship again. I've now effectively had two consecutive turns with one ship against a ship that has had no chance to react.
I can't see how this isn't unbalanced (sat comfortably in my armchair). :wink:
