my only issue would be the controls sure a keyboard and mouse work fine for a fps or a turn based or puzzle game but a hack and slash rpg like kingdom hearts seems difficult at least for the camera but at this point who knows.
Why would i not keep up with it. This series has taught me a lot about dealing with emotion and friendships as well as just being one of the best game series i have ever played.
something that could happen is a reveal that due to the whole weird time-travel thing Sora WAS meant to have the kingdom key Riku was simply a catalyst and was meant to use way to to the dawn from the get go.
