Does anybody know a website that is similar to poptropica or club penguin that you dont have to pay real money - website to poptropica creators account

Some site that does not try to attract children out.
a living thing and I already know about: marapets, RuneScape, Neopets .... I know that many websites, but I want something new.
I know that things that are very popular, but can someone tell me something that is not very common and very funny? Thanks
