It can be difficult to judge games in different genres, including 2d vs 3d.
A horror game just can't be put side-by-side to a board game with any coherent concept of saying one is 'better' or 'worse'
But by voting for each in the same categories we have listed (Art, Design, etc.) we can put them all on a level field, including 2d vs 3d.
The big question is does the game use 2d/3d graphics effectively rather than which style it uses.
