i allways thought that it is kinda stupid that the Phaserbeams allways look the same, no matter how much energy you have put in weapons.
My idea would be to add the stat to the glow (bloom?) value of the single beam.
if you have 125 power in weapons the beam looks brighter -> more damage
if you are hit by some energy drain the beams get darker or even break up -> less damage
the Bloom value can be adjusted by % so there is no reason to break it up into 25 50 75 100 125 steps but it could be as accurate as 1% //edit: ok forget that, the Bloom slider does not seem to affect the beams.
same could be done for shields & engines, (i have no idea how Aux could be visualized)
but, high energy levels on weapons = brighter beams and cannons, high energy levels on Engines = brighter glowing engines, high Shield energy = brigter / darker Shield bubbles when hit.
That just seems logical to me.
And if you get hit by some energy drain ability (breen ships for example) you could instantly see, "oh my beams are too dark, revert energy to gunz!".
As it is, the only diffrence the energy levels show are the yellow numbers above the enemy ship, and they are so random that i wouldn't notice any diffrence if i would look right at it (also they are flying by pretty fast).
not really the more light it gives off the more power is lost in that form, the perfect phaser would be barely vissble and ths delivering the most power to its target.
A perfectly efficient weapon, yes, but the effect would still also dependent on the power of the emitter behind it. 50% of a 100 Gj emission would still be five times as much as 100% of a 10Gj emission.
