BioWare's MMORPG, Star Wars: The Old Republic, will become a free-to-play experience on November 15, 2012. Gamers who wish to pay a fee for a more advanced experience with rewards will still get to do so. The jump from a subscription model was made in order to gain a wider audience. F2P changes will be seen with the changes like addition of Cartel Coins to SWTOR, a new in-game currency, which will launch on November 15 as well.
F2P SWTOR will allow gamers to play all the classes available up to level 50, which is the current level cap. I played SWTOR when it was first released and loved it. If you're on the fence about checking it out, I would suggest trying. It will be free, and who knows, maybe it will be the MMO you were looking for
