Tree os Savior is a free to play mmorpg on Steam that I started playing this weekend. So far I've really enjoyed it and I want to share it. The art is pleasing, there's really cool music and the gameplay is fluid. I have a great time just going out of town to kill things. #KillingIsFun
You start the game by selecting one out of four base classes which after 15 class levels allows you to follow one of two next-tier classes. You level up really fast, and the many choices allow you to form really unique fighters. There's a handy skill build simulator that you can use to experiment and plan your build.
