You know what would increase subs?

Guys, FFXI is never getting a graphic overhaul/remake, just let it go already (the planned mobile version was about the closest they got to it, and development on that was canned long ago).

For better or for worse, FFXIV was what they chose to do instead (as in, the resources and money they decided was better spent on a new game rather than upgrading FFXI's graphic engine.).

FFXI getting an upgrade would probably kill XIV since the former is the better game, the better FF and the better MMORPG, except for people who want to play sims and ERP.
Yoshida would never allow that, I'm pretty sure he secretly hates the people who still play XI over his game
