There are two things about the
FreeStyler that are most likely to bother a gamer. However, it's more likely that only one of them will bother any given gamer, depending on that gamer's skill at 'boarding. Beginners will find that the
FreeStyler is hard to control and is very tiring to use. This is true. For that matter, so is actually using a skateboard or snowboard. In fact, the
FreeStyler is MUCH easier to control - for one thing, you're not actually moving at high speeds!
Those gamers who are more skilled at 'boarding may be sad to find that there's not a way to have the FreeStyler monitor 'jumping actions' in real-life and translate them to the appropriate jumping actions in the game. This would require a lot more technology (and therefore, a lot more cash...) and would leave those beginners scratching their heads in confusion (and disgust...).
So, for the mainstream-ish market (a.k.a. 'a large enough group to support mass production of a product'), the Thrustmaster FreeStyler is the best balance of accuracy and difficulty.
As far as minor notes go, I would have preferred to see the one-handed controller made as a removable controller instead of hardwired. It's far from a major thing, but if I want to use a different controller, I don't see why I should still have to have their hand held controller still attached to the board...
