When you reach this tender age, and if you haven't screwed up somewhere in your life, you should be on decent money, and be earning way more than you need. We all have to spend this surplus money on something... might as well be pinball.
But certainly, no pinball game will ever give you 10 grand's worth of entertainment... that's just silly. I'd rather go to a local bar, play the game a few hundred times in a great atmosphere with friends and your beverage of choice. In the end, walking away seeing everything the game has to offer and only spending about 300 credits. What pinball games were originally designed for.
