Making an island (Actually, in my case, islands) is easy and hard. Making the quests is hard, but making the locations is easy. I've made the main areas of two islands so far, and it's going pretty good. The first quest is partly done, so 3 and a half to go. The whole place is going to be really big, with lots of different areas

Tip of the day: If you need more room for your island(s), then split it/them up into multiple 2D maps. You can then make the island(s) more then 4 times the size!
