It's not really that difficult of a concept, you expand on, or maybe even change, and improve the mechanics of the game as a whole. You make the kinds of changes you simply can not do in a mere patch. Other improvements may be applicable as well, such as graphics, engine, etc, though some of these may not be entirely applicable to Terraria, but could be to other sandboxes.

Sequals don't have to be what happens after the previous game.
