Tabletop roleplaying games, Legos, and miniatures!!
Dungeons and Dragons is basically an excuse to lore-dump dragon information onto his friends (because dragons are VERY cool)
Lego is like... gosh where to even begin???? It's so creative and relaxing and satisfying and it's infinitely collectible and you can trade sets with people and take things apart and redo them and build alternative builds and display them and and and and!
Miniatures are super cool because it's like paint-by-numbers but on a model!
