Whilst we can still buy games, a lot of people tend to play free games now and instead make in-game purchases through these games. Much like my previous thread regarding what was the last game you bought but this one is for the last in-game items you bought.

My last in-game purchase was the Fortnite battle pass for my kids.

That's hard to say for me... I don't usually do in game purchases. I'd say BitLife stuff maybe on mobile.
