Yeah I know, "Let FFXIV do its own thing!" It still is so shut your mouth.

Crossovers are unique in that certain way that is genuine depending on what it is. Not like Yukai Watch which was extraordinarily lazy, but like FFXIII's which had Lightning actually talk to us, even though the convo was one sided :/ Dragon Quest's was actually pretty neat and unique and actually had dialogue choices for funny answers.

Watching your character interact with otherworldly beings just gives the feel of your character becoming more than just another average WoL but one that matches main characters like Cloud, Squall, Lightning etc. Its that sort of universal growth that makes our characters stronger.

Anyways, philosophies aside, what would you like to see for another crossover?

Few thoughts: Nier Automata, Kingdom Hearts 2.8 (maybe with Aqua and Sora perhaps), FF7 Remake, the long past due Phantasy Star crossover, or maybe a crossover with Capcoms Dragon's Dogma.
