A couple months ago I found out about a game called Bloodline Champions through a friend and quickly got sucked in. It's an arena-combat based game that relies heavily on accuracy and timing. I enjoy it because it's a good way to break from some aggravating DoTA games. Here's a link that explains the game in more detail and better than I think I can

P.S. if anybody really is interested in trying this game out send me a message or reply to the post and I can help you get started.
