Novalith Cannon/Kostura Cannon a bit OP
Could use a nerf
So after playing a few games with 5 solar systems I found that its a bit over powered that the cannons can fire across those systems. if the game is set up to kill the home planet of the other players you should at least have the cannon in the same system. Other wise with the support of other players you could just build 4 cannons and wipe out the home planet of each player after sending out scouts, and never need to leave your controlled system with your fleet. Takes the challenge and fun out of the game if all you need to do is bunker down and but up a wall of mines/ships till you fire 4 rounds into the other home planets.
It made the game to fast to win I would suggest changing that or at least add a check box that disables the uses of the cannons across solar systems for all factions to make players move out from there planets and make the game more about fleets vs fleets and not who can build there 4 cannons first.
