Alpha 0.7 is now live.
I've played two games, so far, one that I gave up on and one that I won.
Overall, I strongly dislike the new combat system. It makes combat threats in the early game SO MUCH HARDER to deal with that I don't like playing anymore. Please consider a rollback to Alpha 0.6.2.
Combat points are really hard to accumulate in the first 20 turns, especially when the tech "Tactical Systems" is NOT an early technology (either buried too deep into the tech tree or absent completely). Constructing buildings in the early game was already hard enough, but if a Pirate shows up early it's now even harder because I need 5 Combat points to get back any Production points that the Pirate (or Pirates if a second one showed up) stole.
