I agree prices are a bit steep for the beta. Some of the games I could buy off amazon for the same price as the rental.
Had the same problem with install times. Got the titanfall bundle. I picked up dead rising 3 to play while titanfall was downloading. Dead rising took around 5 hours till I could play. Same thing with ryse it took 3 1/2 hours. I'm gonna keep mine for the Xbox exclusives. Sunset overdrive looks really fun
Then it must be my system. When I talked with Microsoft they said it was normal.
The long install times need to be fixed. Ryse took me 3 1/2 hours from inserting the disc till I could play it
I'm waiting for an update to fix the extremely long install times.
Not sure if they're still running the promotion. If you register mk8 with your Nintendo account you get a free game. I got wind waker for free.
