I'm only the most casual late-bloomer dilettante sort of gamer myself, so I think I'm fairly safe in saying the gameplay here wouldn't be offputting to even a total beginner. It's relatively low-pressure, you can take your time and wander around and explore instead of constantly being pushed into combat situations, and it's not one of those frustrating games where you wind up dying all the time and having to do things over and over just for making small mistakes or not being fast enough.

If you do ever decide to pick it up, since it's an older game for a prevous-gen system it could probably be done fairly cheaply -- however, it might almost be worth waiting for the Wii version that's due out later this year. A lot of Ammy's special powers involve the use of the Celestial Brush to literally paint changes into the world, and that's just MADE for the motion-sensitive controller.
