If you like building in video games, Terraria was just released for Android, and has been available for some time on the iOS app store. The PC/Steam version has more content however, and even has a free major update listed for October 1st. Terraria is a “Metroidvania” style game, except virtually everything is mineable and craftable, allowing you to mold the world to your liking. The mobile version is currently $4.99 for the full version, while Steam has the PC version listed at $9.99. .
