Roblox

Developer: Roblox Corporation

Once upon a time, it might have been easy to write off Roblox as another blocky kids game just ripping off Minecraft. Not only have those days long since passed, that criticism is now entirely incorrect – as well as being a multibillion dollar title drawing in tens of millions of players every day, Roblox is slowly becoming an increasingly respected game development tool as well as a highly-popular free PC game. The most high-profile example is VVVVVV creator Terry Cavanagh’s recent foray onto the platform, but a suite of creators has been using its tools (and making a decent income from them) for years. As the attention offered to it grows, Roblox’s own development could be fascinating to be a part of.
