Sins is a game with a fairly long learning curve, and while two new tutorials will certainly help new players, its really a game you have to spend some time with on your own pace. Before this wasn't a problem as in Trinity you could play any map without any AI players if you wished, but in Rebellion for some reason that feature was removed.
To get around this, I've made a modified small map where all phase lanes to the AI's homeworld have been removed, preventing it from interacting with the rest of the game in any way. It is intended for players who have just finished the tutorials as a sort of sandbox tutorial, where they are free to expand and experiment at their own pace. Player can still get some combat experience if they leave on the pirates (and don't research Truce Amongst Rogues as TEC Rebels), and can even win the game via occupation or research victory if they so desire.
The second version is much larger, features militia from all races, and plenty of fortified planets for you to practice combat on. Can you get the secret victory after fighting through all six titans at once?
