I think Dark Avatar would be even more unique if you could make your own custom weapons. Before you say no, hear me out.
First, I think it would be cool to change the color of your weapons. Altarians in Galciv1 with bright red lasers just didn't look right. So, you could change their Laser I's to teal, or blue.
Second, I think you should be able to make weapons form scratch. After you play the game and get all the weapons, it loses some lasting appeal. Ipersoaly think that weapons should have: Rate of fire, Damage per shot(obviously), range, and accuracy.
Example: you can create fast firing and heavy damaging lasers with high accuracy(and range), but it's gonna cost you.
Example 2: make a short range rapid firing laser, with short range, low-decent damage, and medium-low accuracy. Making this weapon a prime canidate for fighters.
Man, now that I think about it, Stardock would rock if they put this in Dark Avatar!

(cmon Frogboy, you know you wanna make it)
