after playing in Sandbox mode on Trouble Heaps 21 hours, I wonder if I can change the gamemode to like Inferno?
It would be really nice to see big battles in my giant castle.
Thx. - [Is there an mod for more Bricks and stuff?]
You could copy your save file in the maps folder and play it as a new map in Invasion. You'll lose your Bricktrons (will start with new ones though) and your tasks and whatnot. It'll be like starting a new game of Invasion, but with all the bricks you placed there in your sandbox game.
