From Xfire: "Spread out across nearly a dozen different consoles and nearly two decades, there have been quite a number of Kingdom Hearts games released, and let's just say that the quality of the games can vary greatly depending on who you ask."
One of the biggest TV and movie tropes in the last decade has been the multiverse, the idea of exploring multiple dimensions to uncover alternate versions of existing ideas. From both a business and creative perspective, it makes sense why established franchises are shaking things up in this way.
However, there aren't many video games latching on to this trend, as rendering multiple worlds in real-time is a difficult feat and the medium is relatively young in comparison to its contemporaries, making crossover opportunities more difficult. Still, there are a few great titles that manage enough to overcome these challenges, and here are some of the best examples.
NP: “When I played through Final Fantasy XVI, I occasionally found what I believed to be evident Kingdom Hearts gameplay inspirations that I’d rather not detail here due to spoilers. Still, with it having been previously confirmed that Kingdom Hearts staff was working on this title, the notion wasn’t all that surprising.
However, I didn’t realize how truly instrumental Kingdom Hearts team members were in developing Final Fantasy XVI. After digging through the title’s credits, I found crucial Kingdom Hearts development staff who played significant roles in ensuring the combat design excelled.”
For a long time, it's been widely accepted amongst Final Fantasy/Kingdom Hearts fans that Donald Duck is the most powerful mage ever to exist, mainly due to his use of the stupidly powerful Zettaflare spell towards the end of Kingdom Hearts 3. This spell is one step up from Teraflare, a spell which was used in Final Fantasy XIV that was so powerful that it completely wiped out the base game, giving the developers a canonical reason to let them bin everything and start again from scratch.
Now you're armed with this information, you can see how it was pretty surprising for Donald Duck of all characters to bust out Zettaflare and establish himself as the most powerful character in Final Fantasy/Kingdom Hearts lore. However, now that Final Fantasy XVI has arrived and delivered a whole new cast of characters, a new challenger has arrived to provide Donald with some much needed competition.
