Replying to DPZ2:

"Would players with current housing still subscribe at all if they were ensured that the data for their house interior would exist forever?"

Answer: Yes. We could take breaks more often that is true, but many of us would also log back in later on to check how the MSQ is doing, to raid with our FC-mates, to continue our deep dungeon saves, to progress seasonal PVP tracks, and to do stuff on Party Finder.

"What price should a house become in a revamped housing system? Free? 10 million gil? 100 million gil for a Mansion?"

Answer: if we're talking about instanced content then the price as it now works. we could buy a small, then upgrade it to a medium, and finally a large.

"Would a housing instance that can only accommodate a single player be ok?"

Answer: Just have it be like island sanctuary where you can have some friends over.

"Perhaps players should come to a consensus about adapting a single design case for housing, before saying "make it like X" or "make it like it is today, but ...".

Answer: That is not going to happen through a forum vote considering that the majority of players don't even come here.
