Actually looking at the Adventurer's Appreciation Campaign, I think that can be comparable to the Mogtome event (since it just grants players bonuses for this and that). So in a way, that makes FFXI and XIV equal when it comes to events.

FFXI's non-real life based events
Blazing Buffalo's
Summerfest
Feast of Swords
Adventurer's Appreciation

FFXIV's non-real life based events:
The Rising
Moonfire Faire
Make it Rain
Mogtome Event
