Using motion controls poorly or just because they are available instead of fusing them to an interesting idea (Metroid Prime Trilogy is a spectacular demonstration of how to properly use the Wii Remote) has made the Wii Remote appear gimmicky to many gamers. Greenberg says that Microsoft is determined to "avoid those traps."
Asked if Microsoft will actively say "no" to developers that use Natal in any way that seems gimmick-oriented, Greenberg nods and says, "We will very carefully manage the portfolio. We want to focus on original concepts. Not every idea is going to make sense. Halo Reach should be a great game with a controller. It should never be played with your body."
--- See theres the problem. If the company really believes in controlling what games use what controllers both the developers and customers are going to be dissapointed at some point.
Maybe your kids just want to play Carnival Games on Xbox.
re: Halo Reach. Ok fine, so do you want to tell how many of the 40 million 360 owners are going to buy Natal if there arn't any fps's with natal controls?
If theyre serious (i don't believe they are, they will encourage as much casual stuff as possible) we will have another Wii market split, where kids on one side want one game and adults on the other want another.
“When we make some new announcement and if there is no positive initial reaction from the market, I try to think of it as a good sign because that can be interpreted as people reacting to something groundbreaking. ...if the employees were always minding themselves to do whatever the market is requiring at any moment, and if they were always focusing on something we can sell right now for the short term, it would be very limiting. We are trying to think outside the box.” - Satoru Iwata - This is why corporate multinationals will never truly understand, or risk doing, what Nintendo does.
