We've had collectable cards for ages. Baseball cards, garbage pail kids, etc. Those you couldn't even play a game with, you just tried to collect and trade. Honestly even MTG and Pokemon cards are so much better than mobile games which are there 24/7 begging for attention and making kids feel like they're missing out if they don't check in every few hours. Plus with the cards in the end, you've got a collection of cards you can play with, sell, or keep for the memories or whatever. With digital stuff you'll be lucky if you can still access in your ingame purchases after a few years
