Playing around with various display styles for my cubic dungeon crawler. Pic your fave. Although all or most can be included.

With nothing but a fog on.

With a point light on, shading by vertex normals.

Tile shaded, like The Crawl, kinda.

Built in toonshader, didn't work.

Faked toon shading using spheremapping. Kind of works, some visual distortion. But no impact on frame rate.

Faked shading, also spheremapping. Same kind of distortion issues and no impact on frame rate.

Lighting has some effect, toonshading kills things. There's another toon shader I haven't tried yet.
