I do agree with Eddison as well, it sucks that it doesn't look realistic b'cuz of no ship movement to actually simulate what a naval engagement would look like in a '0' gravity enviroment. One game that i've tried that does do this automatically upon engagment is EVE online.
LOL, really that made me laugh hard. espcially that part about eve.
People, really, don't use the word "realistic" while talking about a space strategy game, it just makes us all look like dorks. Unless of course you are discussing the physics of movement in space. But not fleet combat.
Deckard666, good question, afaik, lasers do damage by heating/melting, sort of like soldering, with distance the intensity of the beam lowers over very long distances. and like said before, lasers do need a large amount of power. the limit here in game is mostly for game's sake.
What i would really want is for all ships to have more guns, a little more variety of guns mounted on smaller ships also, of course just for looks, dont want to offset the balance
