I don't really have an active collection hobby. If I did, I would definitely collect figures from my favourite games and anime. I would also absolutely love to collect blades (Especially katanas), but that can be extremely pricey. Hopefully when I get a full time job I can at least begin with the figures 
That being said, as a kid I use to collect, trade and duel with Yu-Gi-Oh cards since it was what most kids did at my old primary school. I still have all my built decks and cards stored in a box somewhere.
