Lol I have tried quiting before but it doesn`t work trust me . There is like this magnet sucking you back into the game eventually. Kind of silly thing to do with the gold though You could of bought something with $80 you would of made off the gold .
Congratulations on having the mindset to quit and actually doing so. As for your account/money, I would have sold it to gain real money so the time I spent on RS wouldn't be completely wasted.
Dropping the cash wasn't a good decision IMO. It would have been better off to sell it or just store it on a mule account while you had quit.
But look on the bright side. Now that you want to come back, you can work on making that cash pile back. RuneScape might actually become more challenging and fun for you while you work for an actual goal now.
Runescape in my opinion is a game that people play because of a lack of something better to do. After all that is what a game is for correct? if you had friends (not saying you don't) to hang out with instead, why would you even want to play runescape?
