If you're wondering just what the Move can do, then you could do a lot worse than giving Medieval Moves a shot. From the same developers as Sports Champions (Zindagi Games) Medievel Moves takes many of the activities featured in Sports Champions (Archery, Disc Golf and Gladiator Trials) and rolls them into an adventure game.
The game is on-rails, and it is undoubtedly aimed at a younger audience, but none of that stops this being a lot of fun, and the Move is put to such good use, that the on-rails element won't bother you at all. The sword play in particular is excellent, with true 1:1 movement for both sword and shield, giving a depth to some of the sword battles which is markedly superior to anything I've experienced with a game pad.
The presentation is nothing to crow about, and despite a good attempt to make varied use of the Move controller throughout the game, some may find the basics of combat a little repetitive. For the budget price it's being sold at though, this is a bargain, and highly recommended for anyone with a Move, but the 8 - 15 audience in particular should love it, as the feeling of swinging your Move so well ties into the action on screen, it really pulls you into the fun.
