I subscribed for a year or so, other than the horrible client it was good. But there are just too many games to play and not enough time, a good problem to have but still. I also felt like I didn't appreciate the games as much when I got them for "free."
I started getting it for $1 per month by canceling and then resubscribing, now you can't do that and I just don't bother to subscribe at all.
Now with just 14 days for a $1 trial it's an even worse deal. This is why I don't think MS should be allowed to buy up all these game companies. Try contacting MS for support. If you can't get through to someone in less than 10 minutes then they shouldn't be buying any more companies. That should be the test for any company acquiring other companies. If they can't serve the customers they have, how are more customers going to help?
