Looking at the pages and pages of crap games in Roblox is a bit reminiscent of a long list of horrid software on a dialup BBS.

Everything popular seems to start as a clone of non-Roblox games, and then goes off on it's own direction from there.

Not Roblox's fault, but it's not a good place for kids to make friends; any kind of contact information must be censored. They can play there with friends made elsewhere.
