Mainly drama CDs, original soundtracks, and official artbooks. I rarely buy small trinkets like acrylic stands or badges, as I prefer media that lets me revisit the voice acting, music, and detailed illustrations anytime.
I also collect a lot of booklets and CDs of titles I really love! I just can't get enough content from the main games and have this compulsory need to know everything there is to know about them (the beta works, artist/writer/seiyuu comments, etc.), also why I collect a lot of art/fan books. I collect little trinkets too only when the art is original and captures my attention, but I mostly like big ones like tapestries and cloths that I can hang up. Nuigurumis too, of course, it's cute displaying them in a corner.
Mainly Acrylic Standee of my fav bois and Artbook of the game if they have one! I hope Wakudeki will releasse an artbook soon enough......I adore the artstyle & visual direction so much, the music too <3
When I really get hooked on a game, I end up buying merchandise like acrylic stands, acrylic keychains, buttons, plushies, and so on.
When shopping online, I think it over carefully and choose just one item that I really like. But when I get the chance to buy merchandise in person, I end up buying way too much...!
