With two players, by our measurements, the game runs each perspective at a CinemaScope-busting 2.7:1. While that view makes better use of the space than two stacked 1.77:1 frames, why not let gamers choose to run across the entire width? If it's a competitive advantage in multiplayer games, gamers should be able to use it in the co-op mode.
With three players, the top window fills the same 2.7:1 frame, while the bottom two stay at the original 1.77:1 ratio. In four-player games, everyone gets the 1.77:1 view.
We're too far into the HDTV transition for games to be wasting screen space or having other perspective issues
. We understand that designers want total control over the gaming experience. But we players want to use every pixel for which we paid.
