It be nice to have variety level of graphics. I understand that would limit custom content, just be nice to have it.
Or the very least 2D and 3D like Grandia.
Grandia (Saturn) is actually kinda hard to recreate.
Even when they ported to PS1, the graphic already suffered and loses its charm.
Grandia (Saturn) has a 3D world with sprite-based characters, but in battles they use a bitmap for the background, because this lets them do 3D transparency over the 2D environment without issues, due to peculiarities of the Saturn hardware.
The PS1 has a nicer effect for getting into battle, but once there has a lower res texture for the battle map, and the zooms aren’t as expressive, whereas the saturn texture is higher res and because of the odd jagginess of it better mimics the 3D environments you walk around in.
Right now it'll be easier to go all 3D than combining both 2D and 3D.
