I disagree, there is only so many times you can play a Starfleet Command game and just want to beat your head against a wall for all the bugs in EACH AND EVERY GAME, even after buying all 3.
But for pure hands on ship combat the previous 3 easily destroy the Command series. Especially with the mod community for BC and KA.
I would have to disagree with your disagree :P, granted the single player of any Starfleet Command game was sub par, but online vs. play is where this game shined. Plus the mod community was and is still very active for SFC, they even released many community updates and patches after the devs went under to make the game even more like starfleet battles, which is one of the best hex based wargames ever also. =)
Check out dynaverse.org, they are supposedly releasing a free updated version of SFC made by the community using t he acquired source code.
