Some games are just better left in the 2D world...
Castlevania = SHOULD ALWAYS BE 2D!
Mario = Can swing either way
Mega Man = Should be 2D
Street Fighter and Mortal Kombat = I say leave as 2D
Tekken and Soul Calibur = Leave as 3D
Zelda = Can swing either way, but always loved the LTTP lookdown view
Final Fantasy = 3D
Sonic = Can swing either way
Kirby = Leave as 2D
