so far in games it depends on the functionality whether its good or not.
In the motorstorm demo the steering is cool. takes getting use to. You can use it for balance, etc. in tony hawk, which is cool but again takes getting use to. The implementation of it in Marvel UA seems pretty good and it lets you know how to use it as you learn to do knew things with it. Resistance used it minimally but very effectively in my opinion. Haven't use it yet in madden. I believe as games progress for the system and developers acquaint themselves with the possibilities of how to incorporate it usefully it will become a lot cooler, but just the fact its there is neat to me....
