I have an idea that someone might be interested in.
I personally want this addition.
It's basically a stock system in the forum that fluctuates relative to the most popular games.
In order to do this, you need to get the amount of times a game is played. Every time the game is played, your stock value will increase.
You buy the stocks in the shop (note that you must specify a game when you buy the stock)
I'm really new to SMF shop, so I would appreciate it if someone coded this.
