Also another one that should come back rpg wise is the bouncer I never had the chance to play it but, it seems to be good from what I hear and shadow hearts.
The Bouncer could've used some more tweaking, gameplay-wise. It was baiscally a 3D Beat 'em up and if the controls were better, might've actually been damn awesome. But yeah, in a way, I agree. It probably didn't get a sequel because of fan reaction, but if they addressed all the problems and fixed them with a sequel, I most definitely would've got it.
Shadow Hearts is a series I REALLY wanted to continue onward. It had the potential to be long lasting like many other series, and if anything, I really would've loved to see the series' approach to other decades. Shadow Hearts in the 50s, one set in the 60s, 70s, 80s, 90s, even up to contemporary time. That would've been awesome. An fantasy RPG set in our world, dealing with "secret history" and the occult, connected through the decades.
It's almost a crime that we'll probably never get a good Disney game like the elder days. Disney Interactive mainly handle a lot of the Disney stuff now. Even if they let Capcom crazy with some of their licenses, Capcom's a shell of what it used to be.
