You allready mentioned half of what I own (Full Thrust and B5-Wars)
The only ones else I own are Battle Space, Interceptor and Leviathan and Silent Death from I.C.E.
BattleSpace
The Battletech space-war game
I wasn´t very impressed by this, but it was ok-ish, as I was a huge BattleTech fan back in the days
There appear to be a lot of new rules I haven´t bought, so gameplay might have improved (back in the days, fighters would rule the sky, and battleships with small (read BattleMech) weapons would seriously outgun warships with dedicated Capital-Ship weapons)
It is also out of print and it seems it is now called Aerotech 2, published by Catalyst Games, miniatures are from Ral Partha
Ok, Aerotech 2 is _also_ out of print and is now integrated in Total Warfare, covering everything, from Infantry to at least Dropships, warships have not been mentioned
It seems this also is not intended for new players, but for ones, at ease with the basic battletech rules, which seems - odd, given that I was unable to find any other rules for space combat in the battletech universe.
Seems Catalyst Game bought streight into FASAs publishing methods, when they took over
Interceptor
The Renegade Legion Space Fighter Sim
Fighters have movements points spent for accelerating/decelerating and turning. Speed is tracked from one turn to the other. Damage, once armor is penetrated, is tracked via a nifty flow-chart (like 4 pts penetrate, 2 dmg pts take out the right side thruster the remaining two go on to hit the right side shield generator and the remaining point hits the powerplant, taking it to half power)
Leviathan
The Renegade Legion Warship combat sim
Similar in movement rules as Interceptor. Weapons are rather limited (Laser-Batteries, Missile Batteries and Crowbars (Spinal Massdrivers) and the damage model is also more simple.
I think you know this, as the armor scheme of Aurora has some similarities to the Renegade Legion way of handling armor.
Silent Death
A Space Fighter sim from I.C.E.
Strictly Space Fighters and (smallish) gunboats. Simple movement points but plays faster than Intercepter/Leviathan because of this.
Damage is applied in a similar way to Full Thrust, with parts taken out at various points on the damage track.
All of those are rather dated and I haven´t played them in several years. The Renegade Legion stuff is out of print, but the rules are available on the net somewhere - found them!
