Its free on humble bundle: http://www.humblebundle.com/store/a-story-about-my-uncle

Hello, as a moderator of the group TotalWar:Arena Giveaways I would like to notify you of a rule change that happened a few months ago:

All members are required to do 1 giveaway per month (regular store price: worth 1 euro or more)

As you have already won a game from here, please consider putting up a giveaway as well in order to remain in the group (check the current monthly thread).
Thanks!
