Gamespot has a fairly evenhanded review of Uru - like a lot of us, they're taken by the idea that Uru is really two products in one, Uru Prime (every time I type that I have the urge to type "TRANSFORM and ROLL OUT!!) and UruLive. They've touched on the gorgeous sights and sounds that we're all sumptuously soaking in as of right now, and there is a brief acknowledgement of the potential that Urulive has for this product.
The nice thing about a Myst game is that generally most folks aren't offended by it - so there's really no contraversy or hyperbole to cut through. Hence Gamespot can put out a review, minus the spin. That's mostly what we have here. To judge the game on it's missing multiplayer - well, I probably would have left that part of the review open ended, but mayhaps they'll return to it in the future.
As I've said before, right now for me, Uru is an 8.5 out of 10. If Urulive delivers, they've got a solid 11 on their hands
