That is SO true. I know that I've missed a few characters that were final act one prizes. At least two I'm certain of. There's got to be more...
And yet I can't even name them right now. I remember being mad I missed them by a small handful of whatever currency it was, but I don't remember the characters AT ALL.
So please, do the right thing. Remind yourself that this is not something you need. It's just a fun time killer. You're not building a critical collection, you're not doing a job. It's only small potatoes compared to your other priorities
Don't give in to their psychological trickery, designed to make you crave their little pixelated images. When you don't get some item in the game, just whisper this one word of wisdom, passed on through generations, known for its ability to relieve stress simply by saying it out loud or in your mind: "phuckitt".
I swear that works!
