I'm pretty sure they can run mabinogi with its servers on how much Kingofrunes gives them.... ..... ... :P (don't hurt me king xD <3 )
I'm not going to hurt you. I know I spend enough but I'm no where close to Kenero's friend. Very rarely do I hit over 1k in a month unless I'm absolutely desperate for something like I was at the beginning of the year. Trying to scale back to save money. My buying hardly is enough to keep things going as it's done a hell of a lot more sporadically and is usually when Nexon throws shinies at us like miku.
As for the game shutting down, I don't forsee it in the next couple years but when it does happen, any refunded NX will be welcome but I don't really care. As far as I see it, the time and money I have spent is entertainment costs that are unable to retrieved. It's all about getting what fun you can get out of the money you put in like spending a large sum of money to go Hawaii or something for vacation. It's better to write it off now before it happens so that the blow isn't that hard.
I already have a few backup plan games that shouldn't fail me in 2 years and if those games do fail, there should be some backup ones there and if not, then that is when I will finally be free of games and can really expand upon my programming knowledge.
Positive and optimistic thinking goes a hell of a long way to not getting your jimmies rustled. Always have a backup plan and always find the positive outcome.
