I would like to see different costs associated with the 3 weapon (and defense) tracks: MISSILE, BEAM, PROJECTILE. What I'm suggesting is that one track is cheaper to advance in for early levels, but very expensive in the upper levels. Another is much more expensive early on, but comparitively cheaper in the upper levels. The third is "in the middle" for the whole tech tree. Maybe this:
EARLY TECH LEVELS:
----------------------------------
MISSILE: cheap advancement costs
PROJECTILE: medium advancement costs
BEAM: expensive advancement costs
MID TECH LEVELS:
-----------------------------
all 3 with medium advancement costs
HIGH TECH LEVELS:
--------------------------------
MISSILE: very expensive advancement costs
PROJECTILE: medium advancement costs
BEAM: medium/expensive advancement costs
This would force you to decide how to plan you long-term weapons development when spending money on your research. Do you want to do an early "Missile-rush", or plan for late-game "Beam Dominance".
