With all the AAA MMOs going from P2P to F2P (star wars, terra, secret world, etc etc) these days.. why hasnt it finally happened to FFXI or more importantly.. what makes everyone so sure it will NEVER happen to FFXIV some day?
It mostly relates to content and player investment. FFXI has the content and player investment to stick around forever if it really wants to and tries to keep up with the playerbase (it probably won't). New games can't compete with FFXI and WoW in these regards, so players eventually go back to them (partially because they have an early adopters bonus... players become invested in them because they had very few other options at the time). For a new game to be successful, it really has to do everything more than a little better than these games, which may retain significant portions of their playerbase for decades of those players' lives.
