Love the FFXI info. While it's about FFXIV, I wonder if it will answer XI theory I have had. I always wondered if Square expected the XI player to jump to XIV.
Last time there was a direct XI crossover event in XI, "The Maiden's Rhapsody", at the same time the ending to XI's last major story "Rhapsodies of Vana'diel" was released - Iroha, the XI character that stars in both stories
was not allowed to return back to XI's world and a XIV character laughed about it, which was a rather dick move - that sort of thing doesn't usually happen in crossover events. they pretty much seemed to want XI players to follow suit and move to XIV.
Abyssea came out around 1.0 and it felt like it was intended to be XI's finale, and grand send off, by just letting players have super-stats in the new zones.
It's funny that XI's Abyssea story is all about failure in an alternate world and XI's players getting to rescue it and be pampered with power boosts in the process to help with that.
XI was always a pretty harsh game toward its players, but XIV 1.x's failure really kickstarted a lot of QoL changes in it to help make sure its players got to stick around and still give money to SE.
If only those QoL changes had been implemented earlier at a more reasonable place, XI might have more of a presence in the wider FF fandom...
Then 1.0 tanks, and suddenly XI got a new expansion that felt incredibly rushed and bare bones upon release.
Seekers of Adoulin gated a lot of its content to account for the bits and pieces released with every update, namely zones, but it also brought a few things that the game should have benefitted from earlier, like quests that actually give EXP. i wish it could have had ore resources to go further, like adding Tartarus, which is only spoken of, but even if it's not my favorite expansion it still had some great story moments, characters, zones and mechanics.
