Just buy yourself 25k and see what you get and how it feels. You'd probably feel the game wasn't worth a dime due to hackers,lag,crashes,degenerate fucks,bad customer service,can't really get much pixels with $25 and many other stupid problems Nexon can never fix. Now with all that you have left, treat yourself to a nice place with your girl for dinner, nice clothes, better games, and other more useful shit other than NX.
Oh nevermind. Too bad you have to spend all that NX since it can't be refunded.
