I agree with this. It's been said before and I'll say it again - we need some way to convert scrap into research. Either that or we need a tweak to weapon costs. It's a little silly to think that a weapon that costs you 450 credits (projectile cannon) is one of the best weapons in the game when fully upgraded. Strikes me that you should continually have to pay scrap to improve weapons.

I'll agree to disagree on the Nuke though. Most weapons aren't terribly effective singly, and are very effective in groups. The Nuke is no different. One or two won't do you much good, but equip 6-8 and you'll notice a difference very quickly. You only need a single nuke out of each volley to get through to decimate your opponents. They're also excellent insurance against ambushes. Very few weapons in the game can deal as much damage as a Nuke as quickly at close range.

Many an enemy ship has jumped right on top of me and gotten reduced to floating atoms a few seconds later after greeting my nuke volley.
