I love the idea of this style of play as a complement to hellblock and/or skyblock. I believe that you could use the same logic as the other plugins by having your survival island be the same as a skyblock island. What could make this game mode interesting would be something similar to... http://www.mineverse.com/threads/multiple-gametypes-mining-world.42533/ You could use this concept though with the idea of islands that have loot on them. So with this, you could build a larger map (that repeats) with a list of say 10 different islands "templates". Each island may or may not have a chest, or some other form of resources that make it worthwhile to visit. Once a month though, this island world would reset. This would hopefully help reduce the need for endless islands and reset loot for players to go gather. I understand that this would require the use of some additional plugins and possibly some custom work to make the islands repeat and reset. If anyone thinks there may be some merit in this idea, I will start looking around for any plugins already out there that may accomplish this.
