Can the mod be added to existing game, or must a new game be started?
Using Space Age, latest version 2.0.32.

unless you are giving the starting town item to yourself via command, I think it should be restarted

That would save a lot of time. Could you instruct me on this command? I suppose it will break achievements. Would it?

Yes it would break; according to the author, "/c game.player.insert({name = "tycoon-town-hall", count = 1})"

Thanks!

Agree with what sharlin says: When you're in an existing game, use "/c game.player.insert({name = "tycoon-town-hall", count = 1})" so that you can place the first town manually.

You need to explore the map to find primary resources like wheat and apples.
