If you already have Heavy Rain then getting the Move edition update for it costs you nothing and you really should try it out. SOme people like it much better, others think the original DS3 controls were better. As a non-motion guy you may fall into the latter camp, but you never know until you try.
Sports Champs is fun, but best with 2 Move controllers. Though I imagine you won't be buying a 2nd Move until you've decided whether to keep it.
The Shoot is also fun (only played the demo), but not wirth the full price (even the Move game price full price).
There's also LBP and LBP2 with Move support.
