I love a company to expand an IP, and explore it in different ways. Just like the Ivalice games in the Final Fantasy series.

When an IP has been left for a decade or so, I have no problem with them retconning it a bit. I mean the original vision changes over time, and I see it first hand with my own work in short periods of time. But I think there really needs to be a long time difference in order to do that commercially.

I am guessing you are refering to the Final Fantasy VII Compilation? My view on that is they've tried to cram way too much in to the timeline of that world that it's just so messy. I wouldn't so much mind a retcon or an expansion on the universe otherwise, especially since it feels like the original game was incomplete or could have been told better.

Direct sequels and prequels can be done well, but generally are not. However, I'm generally of the opinion that I won't ignore the sequels or feel they don't exist like so many people love to do. I would prefer less sequels and spin-offs and more main titles in a series, especially when talking about Kingdom Hearts.
