Golf balls
You buy golf balls, a sleeve of 3 for roughly $5 each for the balls. A few rounds later you get a message that there is only 1 ball left and it's wearing out. So you have to spend more money to buy more balls that end up missing again. That is after you either spend $50 for descent set of clubs or continually rent clubs so you can be competitive with others playing against you. This game is just a hole to throw money into.
