I think it is a smart move, too. If MS is determined to push boundaries with its new console, it will be expensive. With All Access, they will avoid asking for a large initial price. It is nice to see something pro-consumer as of late.
I really don't understand why SP and MP can't co–exist. Both have their own players and fans, and both are successful. Why don't we play the games we want and let others play their's instead of complaining...
