Most lifetime subs offer 3 years of subscriptions so I doubt it would be that much lol... but Whether or not it's worth it is up to the individual person... ahem...

Hey I could purchase it and then suffer a catastrophic accident making me unable to play for the rest of my life lol. How much money I spent on FFXIV would not be the primary concern then. I probably spend more on take out than I would on life time sub anyway... in the end it's just not that much money to drop on a game I plan on playing multiple years.

So I still think its worth it, especially considering that ARR will never go free to play in the near future, if it ever does.
