bit-tech published a review of the Novint Falcon Limited Edition
The Falcon is a fantastic game controller, although I still think a few kinks need to be ironed out. With the circular grip we used the Falcon quickly became painful to use unless you had a lot of desk space to spread out on, for example. Several of us ended up almost up-ending the Falcon completely with some over-enthusiastic swings, for example.Novint Falcon Limited Edition Review
However, just because it is good, it doesn't mean that it'll sell or that it's good for the market. I've been round the block enough to know that selling something like the Falcon, even to seasoned gamers, will be an uphill struggle.
