Well, here's my .026 (Cdn$)

It appears that balance play is going to be a problem... at least initially. However, it seems to me that each of the sci-fi realms is looking at 'empires' at different stages of development. By putting the realms together we need to have a "multi-era" view.

Bab 5 - initial era (growing). Several hyper advanced aliens do have better tech, but not by much. Only a few of the empires have peaked, the rest are still 'coming into their own.'

Star Trek - intermediate era (vigorous). Rising empires are in great conflict due to tremendous growth. The tech levels are starting to peak, but the empires have not become static... yet.

Star Wars - late era (decay). The great republic/empire has peaked in maturation, has become static, and has started into decay.

So what? Well, I think that the relative strength or weakness that appears to be a problem is actually due to us comparing empires that are mostly at tech level 2 to empires mostly at tech level 10. We simply need to "fill in" the lost eras for each genre.

i.e.
Bab 5 - add the more powerful top end techs for when they reach the middle to end game. Maybe they should never get shields, but that's okay, really strong hulls and armor can be developed.

Star Trek - develop more fully the early techs (lucky for us, Enterprise should help) and the extremely late techs. Races from this realm will have the advantage of highly manouverable capital ships (special: dilithium crystals), their weakness will be the absolute lack of fighters (except perhaps the dominion)and relatively slow non-combat speed.

Star Wars - develop more fully the very early techs. I don't think that the SW techs are really all that advanced, I think that much of the 'late era' stuff we see in the SW movies is due to specialized development of a few key technology branches. That is to say, their movement rates are extremely high, but their combat movement is not nearly as high as the Star Trek ships. They have developed excellent fighters, but personally I don't think the turbo-lasers are nearly as powerful as say photon torpedoes and phasers(IMHO). The only time we see missles fired is from fighters at incredibly short range (that is, they have no capital ship missles).

Finally, I think it is important to critically define the ships by relative size, not by the names given to them by the genre. The Star'Destroyers' are late empire ships... they are 1400+ metres in length which is slightly bigger than the Enterprise from Next Gen (intermediate era). Both should be defined as 'battle cruisers' because of their absolute size... this lets players compare apples to apples.
