I used to have all the old SFB stuff from the original pocket versions, to the final commanders edition
I also have the Star Fleet Command PC game. It is about as realistic to the board game as you can get.
I play it pretty regularly, and have a blast. You have to allocate energy, load the weapons, all those great things. Also, all the ships from the game are included, and there are a ton of online modifications that you can put into it to make it even better.
It also include P/F's and fighters, drones, t-bombs, the Kzinti (called Mirak) boarding parties, ECM/ECCM, monsters and more.
You can find it on ebay pretty cheap. I highly reccomend it!!!
