Wife, kids, work...all interfere with my precious gaming time. I get about 15-20 per week in. That number could go down. If I had nothing else to do it could easily be 30-40 as long as it still felt fun.

I've often wondered what I would do if something happened to me and I was bedridden for weeks/months on end and honestly that time would be spent in FFXIV. Wouldn't worry about it at all OP. I would worry more if you were playing a game that had zero social interaction. At that point you would be a hermit.
