Okay, I asked elsewhere if anyone remembered the TSR role playing game Star Frontiers. It would make an excellent reference source for fleet battles, somewhat with the mechanics but more so for the weaponry/technology, mainly when using boarding parties. Another good game, but a heck of a lot more in depth and probably way too much overkill is Space Opera. I know, they're role playing. But, if the devs wanted to take a look at some really interesting ideas, maybe one of them will check it out and see for themselves.
