As time goes on, technology gets better and developers learn more about existing technology.
EA has promised that playing this year's Tiger Woods iteration with PlayStation Move will be better than last year's motion experience. That's because this time around, the team has had a "full cycle" to allow for full compatibility; you may recall that Move functionality for Tiger Woods PGA Tour 11 was only added via patch. Said lead designer Mike DeVault:
"We have full Sony Move support this year. Last year we had a patch that integrated the support into the game. This year we've had a full cycle to dedicate to the Move. We've been able to smooth out a lot of the kinks we had from last year and then also add some functionality."
Many critics and gamers saw problems with the aforementioned patch; the game was one of the first to support Move, and it sort of showed. But now that EA has had more time to familiarize themselves with the new motion-sensing hardware, the new Tiger Woods should play much better. For instance, they've added a first-person camera, which was included in the Wii version last year but missed the Move/PS3 version.
This could be a very interesting year for Sony's motion mechanic. We'll get to see how it works with hardcore shooters, and better games designed around Move will be on store shelves.
