Galactic Civilizations II: Twilight of the Arnor is being worked on heavily. This week we started implementing a new feature that allows players to have the AI design ships for them. So for new players in particular who just want a decently designed ship, they can now get it with this new option.
Obviously the AI is going to be a major element of what we start working on. Beta 5, which is due out later this month to those who have pre-ordered it, will be the first beta with significant AI enhancements. It will also have a host of other tweaks based on increased internal play testing.
The last beta, beta 4C, was the first one to provide updated AI to the minor races. We haven't seen too many reports on any differences in their behavior. We'll be making a lot more tweaks to them. Basically, minor races will behave the same as major races in the final version except that they won't colonize new planets. But they'll invade, research, and just generally behave smarter than they have in the past.
For the past couple weeks, Stardock has had its collective attention on Sins of a Solar Empire. It's been a lot of work to get that out but the results have been fantastic. It's currently the #1 game in North America according to Gamerankings user interest polling. Sales have been phenomenal as well and the first few reviews have been very positive.
In the next week or so, we'll be migrating to an updated forum back-end that should be (in theory) much faster than what we have today. It should also have a lot of cool new features. Naturally, everyone will hate it. 
Most of the Stardock games team is working on the upcoming 4X fantasy strategy game which will be turn-based and have turn-based tactical battles and support multiplayer. It uses a brand new engine we've been developing that allows players to zoom out and see the world as a cloth (Tolkien-esq) map or zoom in to see individual leaves on trees. The reason we've developed our own engine is so that we can have fine control on the hardware requirements. We want people with 5 year old systems to be able to play the game easily (and I mean play it VERY easily) but at the same time allow players with the latest DirectX 10 cards to get an incredible visual experience too. We'll open that up for pre-orders (which will allow users into the beta) probably by end of Spring.
So that's what's happening. Let us know if you need anything.
Cheers!
