so, there's this CCG/tactical turn-based game out there called Duelyst. it's awesome. I'm very bad at it. if you like children's card games like Hearthstone or Spellweaver, and Final Fantasy/Fire Emblem-esque battle mechanics then I suggest this game. it's free, it's fun, and I'm a baddy. edit: it can play in a browser but there is a client for it as well. small-ish download, patch 0.59 if I'm correct.
