I played the beta for Sins, and frankly I wasn't too impressed, it was mostly an issue of weapon effects, sounds, and design. Though I have to say the whole planet to planet style of fighting reminded me of EaW and Rebellion. I remember thinking: this would be great with Warlords.... leave it to Evile to make it a reality! I found the whole "gravity well" idea interesting, would it make for more effective interdictors?
