3d games meh :\

I play a lot of (very ugly) hex-based games because, the way I see it, companies put more effort into enhancing gameplay if the graphics don't matter.

The XCOM/UFO series might qualify, since it started as an isometric "fake 3D" game at first (or 2.5D, whatever). I never played the later 3D remakes like UFO: Aftermath, but I get the impression it didn't make much of a splash in the marketplace. I don't know if that was due to poor design, or the essential flavor of the game not surviving the move to full 3D, or just the gaming market having moved on from turn-based to realtime strategy games. Maybe a combination of the three.

Others do though, and I don't think a general case can be made that moving from a classic 2D or 2.5D game to full 3D is necessarily a bad thing. It just depends on the developers' skills, and priorities.
