I said it First, Sins 2 for real though
Re: Sins of a Solar Empire II. There have been no public announcements on it. Sins belongs to our partner, Ironclad Games. However, I suspect a Sins II will use Nitrous.
Re: Nitrous. Oxide Games owns it. It is being used on Ashes right now and Star Control (which is in development) as well as some unannounced titles.
Re: Pricing. Sins of a Solar Empire: Rebellion is $39.99. Ashes in early access is $39.99. It'll eventually be $49.99 at release.
Re: Sins development. Sins Rebellion was developed by Ironclad and Stardock together.
