Noita (<- Minecraft)
A short Hike (<- Webfishing, Stardew Valley)
And just a suggestion: since you mentioned that they had a switch: Maybe try finding a used copy of Animal Crossing : New Horizons and bring it at that convention (this would be an amzing suprise but pretty costly depending on how you intend to do this 13h trip)
I’ve never really gotten into terraria, to much “what am I supposed to do now ???”
