I'm so tired of people saying "Gameplay over Graphics". YOU NEED TO HAVE BOTH OF THEM FOR A FUN GAME. THEY ARE BOTH EQUALITY IMPORTANT. Gameplay is simply what makes it fun, but having good enough graphics to fit with the style of gameplay. The more real the graphics are, the more you forget about reality.
It's like seasoning food. You need to have both the seasoning and the food itself for it to taste good., but of course everyone has slightly different taste.
ALSO... 8-BIT AND 3D DOSE NOT LOOK GOOD... AT ALL. I don't blame indie developers for using it if they could not make better art, but saying it's "stylized" does not always excuse the fact that it looks like crap. I hope Notch can get Minecraft to look a little better with his new team.
