Maybe link to an about page. Dropping me straight to a login/create account is off putting. I'm sure it's a fun and interesting game but I want to know something about the content before forking over bits of PII.
I mean it could be PII, but it doesn't have to be. Just randomly generate a username/password. If your name is john smith there's no reason why you need to use "jsmith" as your username for every site.
Yes but it requires effort to create an account and remember a password, etc. and there's no incentive to do that without an about page or some other information about the game.
Just so you know, you are technically losing the game right now :)
