Thank you for taking the time to playtest PA3.
1) there is a typo there, anyway just whatever die will do, but I will specify to use the ol' regular six-sided die needed for the game
2) It will be difficult to answer here since I haven't played it myself. The point in my head was to create situations where even without fuel or just a couple more FP than your opponent, you can exploit the inertial movement to sweep out the enemy's satellite fleet.
For Example: if you are on an orbit with a +1 speed counter, given enough turn you will encounter the enemy's sat and be able to shoot at them, just by using the inertial movement.
Anyway this will definitely need some testing. Maybe I will add a "just 20 FP" mode for quicker games (but with different objectives though)
