Launched in 2006, the multiplayer sandbox title is known for its iconic blocky style and vast array of player-generated games, with some hitting the mark and others not so much. While players can do much more than just create and play games, building and playing unique user-generated titles is still at the heart of the Roblox experience for its legion of fans.
