Final Fantasy XI will be coming out for both the Playstation 2 and the PC, and both versions are capable of playing with each other. The way the controls are mapped out for the PS2 is very nice. You can accomplish all the necessary commands from the PS2 controller, but having the keyboard is a huge help. The keyboard allows for many hotkeys, making the gameplay smoother and less of a hassle. Also, chatting can be done via an in-game keyboard for those PS2 owners without a USB keyboard. Final Fantasy XI also supports the use of a USB mouse, making for a very PC-like experience. Personally, I like the Dual Shock/USB keyboard combo. The Dual Shock takes care of all the necessary commands and is easier to control your character with, but for some of the deeper commands and chatting purposes I like to have the keyboard handy.
