Playable completely without the aid of a computer or similar device. But hey... it's a game and libre licensed, so it is not really that OT.
So this ominously named "Black Flag Games" collective has recently jumped on the Kickstarter hype and seems to have quite successfully financed their game by it (but you can still donate to the cause). Currently they are at $5,932 of their $3,500 goal with 22 days to go.
I noticed it because they already started releasing graphics on OGA under the CC-by-SA license as promised:
Personally I am looking forward to this, as I actually proposed something quite similar in my long running "game design brain-fart" thread. Luckily for them I released these ideas into the public domain... otherwise I would be sooo suing their a**es off :p
P.S.: viva la revolución... errr I for one welcome our new Kickstarter overlords!
