Nice...
Hmm... you seem to have misspelled "research" in several places...
Ummmmm... did you realize that Shielded ships are invincible??? The shield component, by having 0kT structure, will never get hit, and thus the ship cannot be destroyed!
Why don't you remove the Armor and Hull components (in SE2 they're useless anyway) and just give the Shield 10HP, 0 shield points, the "hit first" ability, and an Armor Regeneration ability of 0? Then the shield will repair after combat as it should. (Actually, DID shields repair after combat in SE2, or did they require a spaceyard? I really can't remember...)
Eek! The control center has zero hitpoints as well! Now ALL ships will be invincible!
The fighter spaceyard has zero HP as well...
Clever idea using disposable drones for research, though!
And setting the refit cost for comp removal to a ridiculously high number to prevent true refitting... I like it!
What's up with the ship movement speeds? I put 4 engines on my escort, but it moves at speed 6??? Is this supposed to account for the different system sizes in SE2 and SE4?
Why is the L2 science bay so expensive compared to the L3?
Too bad you always start with some organics though... that makes early research go too fast...
