Nice idea, I usually see if I can beat ?? Sure you can. You need to anticpate ahead of time that you'll want to do so, and save the game before you make homeworld and discard selections (v0.7.5). If it turns out it wasn't worth saving, then go ahead and delete it.
him it, if I choose a different action in the last round. A "Restart Game"-Button would help, because you can´t save a game before you select your starting world.
