Well if you are really opposed to "Arcade" gameplay then BSM isnt the game for you.
One thing you have to understand about BSM before you buy is that the game is Very arcady, very unrealistic and is anything but openended..... Its actualy quite limited unless you play multiplayer
You dont have the same level of control over ships and the situation as you do in PS and dont look down on your units. Its not a RTS like PS. What you do have though is a very nice looking game with great battles and a good laugh with your mates.
PS allies is a remade version of PS from what i can tell , with more units, options and a gameplay overhaul. If i were you i would try the demo of BSM and do a little more research on PS Allies before considering which way to go.
Hope this helped
