A:Answer Yes but.......
"Any USB keyboard will work with the PS2 and PS3". "If you want to use a keyboard instead of a controller, most games won't let you do that. There are a few games that support keyboard and mouse like Unreal Tournament(PS2), Half Life(PS2), and UT2007(PS3), but most will only allow for inputting text like FFXI and Metal Gear Solid Online."
