With a mment like that its clear you are not a gamer, which is fine as we are here as investors. Logging in using facebook, google etc is not something new, we have been able to do that on mobile games for years. The games are free in the same sense mobile games are also free, but we all know what happened there.
Now, as a investor this doesnt make it a bad investment, like Crypto im sure there will be many young ones dumping their $$$ into games like these.
