Hello, i got my beta key today!(yay!) so i want to capture my entire experience with the game, and i thought i could do so, by streaming me playing it( i have been keen to do that for a while), but as i'm aware the game is still a beta and i will only do so if the developers think it is ok to show the game to others in it current state. Also i plan to stream on twitch.tv and they only allow to stream games if the developer is ok with that. I think that streams are something good to the game as is free publicity, and many games get huge boosts in players thanks to streamers, i will prob get very few people watching anyway, since i lack any type of e-fame whatsoever, anyway, will wait for an official answer.
I think someone else has done this, so you may want to check to see if they got explicit permission, but I think there's no NDA in place.
There's info in the FAQ about this: http://www.cardhunter.com/game-info/ Short answer is: yes, but please note that the game content is copyrighted by us.
