You read that right - Dungeons and Dragons Online is going from a subscription based service to free to play!
"Yes, for real. DDO Unlimited is free to play as long as you want without subscription and—most importantly—without your credit card digits. Just log in and start battling your way to elite status without so much as reaching for your wallet. Along the way, you'll even earn points equal to your level of success to spend in the DDO Store. It's like we're paying you to play! " -DDO.com
Coming later this summer, it is now in BETA. Stay Tuned for more information as it becomes available.
