That annoyance is a good business practice though. The free games for the month may not be enough incentive to certain people that may be considering subscribing, but you potentially seal the deal by offering exclusive content to that group that is willing to pay some extra. There are enough perks that I can see the cost being worthwhile.
Also, oh shit, this service is taking awhile to really get off the ground. I knew I had heard about it awhile ago, but it's over a year old at this point. At least they're sticking with it though. Not sure exactly how large their customer base is at this point.
I am a little bit interested in trying the service, but my connection is so terrible up here, I don't think I'll bother.
