Tabletop RPG. I started in High school, you need only paper a pen and a set of dice, right ? All the rules can be found online anyway, right ?

But it's so much better to have the physical books. And you need more than one dice of each obviously. And this nice metal dice looks very good. I obviously need different set of dice with colors pattern that match my different characters.

Speaking of characters, I need mini. I could get the cheap basic one of course, but the lead ones looks sooo much better.

And I obviously need custom models for all my characters.

Several years later, with a disposable income and I added maps, tokens, terrains, cards, ect. Even a tablet that I use only for this. I'm now limited by the storage place available in my flat (maybe for my own good).
