I think the game needs more chaos. So, here are some completely untested rules changes.

1) After playing events and setting up movement, roll a d6. Everyone passes their initiative chits clockwise that # of players. [So nobody can plan on the knowledge that they go first on the first action].

2) Players may play events in a movement slot, instead of during the event phase. The even happens then! You don't get to redraw a card and don't get to move. Useful for springing an unexpected planetoid. Major events must be played normally.

3) At the end of Slots 2 & 4, everyone can fire their laser! Only against people straight ahead, of course. Roll a d6. If it's >= distance then you hit. 1 damage. [Helps trailing players ding the leaders.]

(For a bloodier game, make lasers fire at the end of more phases).
