Well,
BFG is actually the first miniatures game I ever played, and so it is what got me hooked on the hobby!
Overall, I thing
BFG is a great game with a lot of fan support (make sure to check out the Port Maw website!). The rules are reasonably balanced, although the addition of some of the later fleets have created a couple of odd rules ambiguities (none of which are too major). The only thing you have to remember is that since
BFG is a specialist game, there isn't a lot of "official"
GW support. The last new ships to be released where the Adeptus Mechanicus vessels back in '07. The basic rules date to the 1998 time frame, so there are a few mechanics that aren't commonly seen in games now adays (for example, the game uses a Gunnery Table similar to the Epic
40K rules, which makes since as Andy Chambers was the lead designer for both games).
Never fear,
BFG is definitely a robust game! As for fleets, the Chaos fleet is actually about as fleshed out as the Imperials are as far as number of models. The Eldar and Orks aren't too far behind. The Tau actually have two miniature ranges; one from
GW, and another from
FW. Dark Eldar, Necrons, Space Mariens, and Nids are a bit less well off, but then again it is really easy to scratch-build an awesome looking Nid fleet from
40k bits.
The rules aren't as complex as some space games you might have played; there isn't a "ship status card" per se, like you might find in
B5 for example. Each ship does have a certain number of hit points associated with it, and certain systems (port weapons, stbd weapons, engines, and the like) can be damaged by critical hits, so there is some book keeping involved You should also talk to Horizon; he is the editor of the
BFG fanzine Warp Rift, which is a great source of info on the game.
So, bottom line, I highly recommend the game. It is a lot of fun, and helps fill in the gaps in the
40k universe (ie, How exactly did these armies get here?).
