Of course, speaking in terms of the video game console generations, the PlayStation Move will easily prove to be the best one available out of the big three. The footage being shown at the Game Developers Conference of 2010 is definitely confirming this thought.
The PlayStation Move is the name given to what was formally known as the codename Gem for the PlayStation 3. This motion controller comes with a wand and a peripheral that is used to hold the buttons and joystick for movement. This set up is similar to the one that the Nintendo Wii makes use of for the Wii Mote, but the Wii Mote is a lack luster device so it does not matter. When people think of the PlayStation Move, people should generally think of it as what the Wii wishes it could be.
The PlayStation Move has about 1 fps lag, which is equal to the lag on the dual shock controller. So the time it takes you to press a button and for the action to be displayed on the screen will be equal to the amount of time it takes for a movement to be registered with this new motion controller for the Ps3. What makes this device in particular special is that this will be the true motion controlling device for video games. Instead of allowing you to make a movement and having it translated into a preset motion directed by the game developers, there can now be true 1:1 movement recognition. Which, I believe, is the ultimate goal of motion controls for any video game console.
The demos shown at GDC 2010 for the PlayStation Move were fairly impressive. These demos offered situations such as you being an underground fighter and you having a fist fight with a foe, archery and gladiator battles. These are three situations that can best display how efficient this motion controller is, as these are all events with which people generally wish that had complete and original control over. With that being said, the gladiator game did not have 1:1 motion sensing, I heard, but something quite close to it. As for the underground fighting game, titled Motion Fighter, I believe it does have a 1:1 motion control detection, but it gets criticism for having a sloppy control set up.
All in all, the PlayStation Move is making its first impression out in GDC 2010, and the impression appears to be a good one. This device is very versatile and can be used for both hardcore gamers and family mini games, which is desirable for a product, unlike Project Natal and its regrettable interface. Be sure to look out for the PlayStation Move, it will be coming out some time soon.
