Roblox

Roblox is a free online brick-building MMOG (Massively Multiplayer Online Game). It entered multiplayer alpha in 2006 and was released in full to the public later that year. In Roblox, the player can visit, build, and script Places, using an infinite supply of virtual blocks, and the scripting language Lua 5.1. ROBLOX's name has varied over time, with the first few names "DynaBlox" and "GoBlox". Even then, these domains now redirect back to ROBLOX.
