The closest we got to this was when Razor, Dragon and I went out on an exploration mission..
On an unrelated note, but related to the thread, I think I'm going to rebuild all of one of the lighthouses from Golden Sun on single player. EVERYTHING. Unless it requires uber-redstone wiring, I'll build it. Oh, and the elevators won't work. Any thoughts on which one? It's almost for sure Venus, that's second easiest to Mercury. Mars would be overkill, and Jupiter would be unnavigable.
