We've spent the last several weeks designing, discussing along with learning Unity 3D.
We are moving ahead with some initial design concepts and really striving to make Skyport Alpha not your run of the mill space trader.
The one design concept that is at our forefront is Multiplayer. It's critical that we get a really fun game where a single player and a team (2 - 6) can play.
Our initial concept is where you can run a stand alone "server" and then join that server with your client.
While we are re-focusing the targeted devices to be Mac and PC, ideally we still want to release an iOS version at a later date.
