I've been wanting to stream Guns of Icarus, but some of the most streamable stuff, the crew banter, is just hard to stream when you're a part of that crew. You have no time to interact with and entertain your audience when you're trying to lead your own crew. The game's got wonderful spectator support, but the matches are eerily quiet and calm.
What's wrong is that you aren't able to spectate on deck and listen to the crazy shouting and innuendos, or listen in on the captain-to-captain strategizing. The utter chaos of the chatter is entertaining itself, so it's a missed opportunity to be unable to stream the personalties playing.
