I'm excited to see how island sanctuaries works out- I hope the customization is unique to each person- like us placing buildings/ foliage etc where we want rather than it be a fixed location & be a copy paste of everyone else's island
Unless Island Sanctuaries has a house that I can enter/ decorate it'll be more like harvest moon just without a place of resting- Harvest Moon let you have a house though it's just buildings were fixed but could be upgraded.
They should also let us pick themes for our decor.
What would really sell it is some form of animal husbandry- chocobo breeding, seeing baby chocobos etc. Not for racing, but purely for populating the island & quests/ achievements etc/ fertilizer for crops
Island Sanctuary really needed instanced housing though. It's funny to see the XIV team pretending everything is fine, or they're just obviously avoiding the fact it's royally screwed up
