3D graphics doesn't mean blurry or ruined. Take a look at Civilization IV. That's how you do 3D in a traditionally 2D genre. Sure, most times, companies screw games up by making the move to 3D, but that's their fault for being stupid and not doing it right, not the fault of the 3D, itself. Civ4 (and Pirates!, which used the same engine) set the bar for how to do 2D gameplay with a 3D engine and, hopefully, future games will follow suit. From the screenshots of EU3, I think that they're on the right path.
Anyways, don't trash 3D; trash the developers who have screwed past games up with inappropriate use of it. They're the ones that you're upset with.
