Potatoman Seeks the Troof isn't a live-action agriculture roleplaying game as its trailer would lead us to believe (unfortunately), but it does look intriguing in its own right (fortunately). Potatoman comes from indie developer Pixeljam, and it's available for PC and Mac now, solo for $3, or in a variety of fresh Pixeljam bundles, spanning the Trilogy, Octology and Holiday Bonus.
The Trilogy costs $5 and includes Potatoman, Planeteri and the Bitku beta. The Octology doesn't include any squid-like sea creatures, but it does have all three games in the Trilogy, along with Snowball, Marathon of Doom, the Potatoman soundtrack, Pixeljams Volume 1 album and Dino Run SE. For $15, grab the Holiday Bonus, which includes all of the above goodies, along with the Dino Run text adventure and Beezlebuds alpha.
The above cinematic trailer for Potatoman Seeks the Troof, however, is completely free.
