True dat. Though we enjoyed the game at E3, it's unproven how long the fun lasts with tennis (from our limited play test). Regarding Baseball, Casamassina contends: "When you want to throw a curve ball, you don't actually motion it, as you might suspect. No, why would you want to use a gesture for a console whose primary purpose is to promote unique and innovative ways to play? To throw a curve ball, you first select it on the D-Pad and then make a standard throwing motion."
Though no one should be expecting deep gameplay from the pack-in, a flick of the wrist puts spin on a moving bowling ball but not a breaking curve? Bush league.
