Now, that said, occasioanlly we'll pop in a special type of missile, mass driver, or beam weapon that goes against the trend such as the "Nano Ripper". And there are some evil weapons technologies that buck the given trend was well such as the Psyconic Missile.
Looking at the above:
The Black Hole Eruptor is pretty usless on fighters. But it's absolutely devastating for the player who has capital ships and lots of money to burn as they could have ship that maxes out at 100 attack (in theory). Of course, it would also cost over $1000 (and $30 per turn).
At the other end would be the Black Hole Gun -- a little gun that shoots quatum black holes. One could stuff 2 of these on a late-game fighter for 40 attack (when all Minit techs have been used) and crank them out for $300. So you could build 3 fighters in the time it would take to build that single capital ship and have 120 attack. Those 3 fighers would use 6 logistics to the large ship's 5 logistic ships (capital ships here are using large hulls, not huge hulls).
But moving the battle later -- Player A could crakn out 5 fighters while Player B has only cranked out 1 of those capital ships. Now that capital ship is attacking on a 2 to 1 disadvantage. But then again, the capital ship has a lot more hitpoints. The tiny fleet would have 30 hitpoitns total (6HP x 5 ships) while the capital ship would have 20 all by itself. And each blast of its canon would take out a fighter. It would be an interesting battle.
It would be interesting to see someone make a little VB program that simulates outcomes.
