Shadow Hearts - Probably never gonna happen, since Sacnoth/Nautilus is dead, but since much of the team is at feelplus, I guess there's always a slim hope.
Legend of Dragoon - It's only been about 13 years, it could totally happen! Er...
Silent Bomber - So much fun, but so far under the radar, it might as well have never existed.
Strider - Side-scrolling action games don't get much better than Strider 2.
Dangun Feveron - One of the best Cave shooters ever, but since it's never been released on console, most people overlook it. Effing brilliant.
Ninja Warriors Again - I've always had a HUGE soft spot for this game, and it'd be fantastic to see a modern iteration.
Progear no Arashi - Cave meets steampunk. How could anyone not love that?
Vampire Savior - The HD collection is a start, but I want a proper sequel!
I'll probably write more later, but for now, I'm off to grab sushi for lunch
