Shining Force!
It's criminal that this series just disappeared right when it really hit its stride with the third game(s).
Oh and another non-metroidvania Strider would be sick as well!
(I liked that metroidvania just fine, but it really is a completely different experience)
Also Thief! But like, another actual Thief, not whatever the hell that reboot was.
A year or two ago some fans actually released an absolutely incredible mod campaign for the original Thief: The Black Parade. That project really showcased just how much gas was still left in that particular tank.
