Star Wars is a really big deal everywhere and that includes a medieval destruction simulator, Besiege.
The droid know BB-8 is one of the new characters in Star Wars: The Force Awakens and gaining in popularity. So much so that players can now play as the droid in the build-and-destroy game Besiege on Steam. A community creator MrMcRush used the in-game tools to recreate a functioning BB-8. And unlike the film, MrMcRush has made this BB-8 out of wood, so be mindful. All you have to do to play the character is subscribe on the Steam Workshop and load up the Besiege sandbox mode.
Besiege is still in Early Access for Linux, Mac, Windows PC. Which also happens to be on sale for $5.59 USD, through the Winter Sale 2015. There is a ton of things you can do with the game and for the price, it is very worth it, with an Overwhelmingly Positive rating on Steam.
