Hi everyone. so I was thinking to quit the Game to focus on my life more and the only way is by deleting my fav game so what's the process for this thing?

this thread is from 2007 but I think it still works the same way:

email the devs or just leave it.

Or set a long random password.
Maybe write it down. That way you can use the account again in some time but without the danger of "accidentally" logging in. good luck.
