We know about Dota2, a few of our team members actually play it. Awesome game, awesome characters, we'd love to have a Pudge or a Lina avatar etc.

However, we need permission from Valve to do that legally, we can't just add an avatar which we don't own the rights for.

Last but not least, FaceRig allows 3D model imports :) So while our hands are sometimes tied when it comes to created avatars of character we don't own the rights to, our community is free to create and import whatever their heart desires!
