Got a great deal on 256 GB SanDisk Ultra microSD cards.
Bought 4 x 256 GB (so 1 TB in total) for 30 €.
It's time to label my SD-card-adapters with stickers, which show logos of the game series on each microSD card.
One of my microSD-cards is filled with all compatible LEGO games, one with all Telltale games (+ Life is Strange + David Cage), one with Emulation stuff. The next ones will be filled with Assassin's Creed games, Batman Arkham games and Tomb Raider games.
Maybe one micro-SD card with racing games, logo will be a car.
So far I've prepared these logos, but perhaps I'll change them:
