If I think i’m gonna play it more than once or twice, I’ll put down some money. Like D&D5 is kind of an investment, but I’ve probably played a dozen times now for ~3 hours a pop. Cheaper than a movie ticket per go.
If it’s something I think is cool but will likely never play, I’ll probably nickel and dime a small collection over time. I don’t do that like I used to 10-15 years ago, but every so often I get excited despite my better judgment.
