Ummm maybe try describing your idea more and expanding on it a bit first before posting it? Read though the pinned threads at the start of the suggestions category.
1)What rare items would there be?
2)How high would this island be?
3)How large would it be?
4)What would be the risks of reaching it?
5)What kinda terrain would it have?
6)How would we get up to it? (pillaring? Swimming up waterfall? Ender pearls etc)
6)Ever heard of the Aether mod? (try that first)
You are going to have a hard time of convincing anybody with such a poorly thought out suggestion, I suggest you go think about it some more and come back and write a much more complete post. At this stage, no support from me sorry. But try again dude
Yeah,just need ALOT more fleshing out and what not. Should have read the forum rules regarding sugesstions too. I mean I could start a thread just saying, Hey guys how about bigger boats? or I could go into detail to explain my idea. Pics maybe? build it in creative to show us what you envision (pictures speak louder than words)
