We might consider that but it would limit some of the possibilities (like loser pays) which I think add a bit of spice to the proceedings.
The $39.99 option gives you 60 credits and a guarantee of 60 hours play. Bearing in mind that you'll likely be receiving as many challenges as you send out so you'll likely be playing 120 games before you could possibly run out.
There will also be a number of ways to 'earn' extra credits. I'd be amazed if anyone buying the biggest pack ever ran out.
We're running it like this mainly because it reflects our costs. We have to maintain a server and pay for bandwidth (as well as continuing development of the client software) so it's more like service than a product. It also means we can make the software free to distribute and not worry so much about piracy.
The testers so far are getting better than the estimated 1 hour per credit.
