My son plays a lot of BC online, and managed to collide with with another team member's ship whilst in warp between star systems.... made for the best spin out and explode crash ever....
He also managed to come out of warp, in another online BC game, and crash his Excelsior Class heavy cruiser into another team mate's Excelsior, who had just come out of warp a few seconds earlier.
My son does complain that BC used to lack a lot of the weapons and tactical options that SFC has, but these things have been added by fan support, such as shttles, boarding parties, fighters. The main thing is that BC allows new weapons and their associated graphics to be added into the game.
I've watched a UES Armarillo firing Pulse Cannons at a Romulan War period warship. The Pulse Cannons were an added in extra to the game. Try adding in a new weapon, such as this, into SFC and you'll run up into a brock wall.
BC has the same amount of fan patches and model support as SFC does, so I'm not surprised that it has so many votes.
Over here, in the UK and Europe, all versions of SFC were very hard to find in the game shops, especially SFC 2 OP and EW.
SFC 3 didn't even appear in the shops over here.
