IGN has posted their hands-on preview of FIFA Online.
Quote:
"The most explicit addition, however, is the new control system. FIFA's toyed with total control before; FIFA 09 on the PC ported some of the control enhancements introduced by the Wii iteration, with play dictated by mouse sweeps and clicks, working in conjunction with the keyboard. FIFA Online takes this to its extreme, handing over control entirely to the mouse."
