It's fast, fun, easy, and capable of requiring multi-level strategy.
I got into it through the B5 RPG's Earth Force Sourcebook (Grab it if you can... it's quite worthy, fully compatible, and has some additional nifties, like the various races fighters are not identical... and counters which give a great base for use with FT if you dupe them, and an additional drive type, plus a range of really good ships).
I hope 3rd ed comes out soon... and includes the additional weapons types from EFSB.
