I had long since sold my PS2, but I just wanted to play the next Final Fantasy game so badly, that I bought a PS2 Slim just to play Final Fantasy XII (which I'd go on to buy like 3 more times). I don't think I used that PS2 for anything else, and sold it shortly after wrapping up FFXII.
I also put more than $300 into Gloomhaven, the board game, as it was expensive itself plus I bought sleeves, organizer units, little custom dice, and other tools to smooth out the experience. We played that as a group for almost 18 months and ultimately wrapped it up, so it was money well spent, I think.
