Original Commentary

It... hasn't quite dawned on Kimberly just why losing five hours of game play would be a bad thing... that's like one intense weekend of playing (not counting the time Brisbane and Kimberly were broken up and he did nothing but play). She just assumes he likes to play for the sake of playing and numbers mean nothing to him.

I think the 10% rule is from Maple Story... or was it 5%? I forget... but it's still a nasty thing when that 10% = five hours of your life you'll never get back. Stoopid green slime bunnies... -Isabel

Modern Commentary
You don't lose xp in MapleStory when you die any more. They've been slowly removing the old systems that aren't fun and replacing them with new ones.

As Katelyn said several years later, about losing progress in FBAO "If you enjoy this game, then what's the problem? Now you get to play more.".

I disagree with her but can't explain why - Terrence
