Of course, most of my exposure to military-sci-fi has been through things Derfmancher has lent me, which probably has to do with it, too
Anyway, here are some reasons why an insect-like race could work well if they were our third race:
- Deadly insects are cool. I know I already said this, but it's true

- It makes sense that the population of insects could explode in a very short amount of time. This goes well with how the units vs time is supposed to work for the third race: that is, the third race should have only a few units early-game, and lots of units late-game.
- Currently most types of units, within a race, have rather-unique looks. Having a race made up of one type of insect would give us the chance to design units that are similar-looking, which would help to differ the third race from the Core and Chronolith. I know this isn't huge, but I think it would be nice

Derf had an interesting idea that we expanded on: the race has a unit that increases its population cap, rather than a building. I'm going to call this unit a "queen," but that's just because that's what Derf and I were referencing it as; it really could be anything.
Each queen you build raises your pop cap by a set amount, just as if you were building a pop-cap-raising building. The interesting thing here is that the queen is actually a fairly-powerful unit, to the point that it's a good idea to use it in combat. As you build queens, the cost per queen rises exponentially. You might start out paying 15 matter for your first queen, but by your twentieth you might be paying 350.
The effects of this could be very interesting. You're provided with a variable pop-cap, but it has its price. You're encouraged to constantly attack things because once you lose a tons of queens and units, its incredibly cheap to rebuild them, and you're discouraged from sitting around creating a game-ending mass of units because it's insanely expensive to do so.
What do you guys think? If possible, we'd like to avoid naming specific books, movies, and such that we like the ideas in, due to problems with copyright-infringement
P.S.
While reading the last segment of Derf's and my chat log, I realized that we had actually talked about it taking an exponential amount of time, rather than resources, to build a queen. You're therefore forced to either build more buildings capable of producing queens, which could be pricey, or to constantly sacrifice your queens so that you can build new ones more quickly.
