Glupinickname, Some things I saw at this week's scifi convention in Zagreb:
people selling pretty faux-retro editions of old Victorian science fiction and adventure novels, which is neat! Except that, for some unfathomable reason, books use Comic Sans font for the text.
there are also folks selling hand-crafted D&D dice for between 70 and 140 euros per set. There might be ttrpg geeks out there with enough disposable income to spend so much money on a single dice set, but I sure as hell ain't one of them.
