Bioware has done it. Their immensely popular MMORPG, Star Wars: The Old Republic has gone Free-to-Play and it’s not even a year old. You can play as any of the 8 classes in the game all the way to level 50. They don’t even ask you for a credit card to create an account. Impressive. Most impressive.
