I cant see how designs were shitty since it was a very basic product placement with a logo, If anything its a start... But peppy specifically stated that the print quality sucked.
As for an answer to the topic title... I want a pippi dakimakura that I can cuddle at night while thinking of peppy XD at some point when I get up off my ass I'll do an image, purge the print heads, grab the press out the garage, pick up some peach skin poly and make one... Muwahahaha
what I would like to see is not an t-shirt but an good quality long-sleeved shirt! It is usually a bit cold in Finland, and t-shirts are most of the time not usable without being buried under a jacket D: (tho atm I am dying in heat because lol summertime ;D) edit: or a hoodie too
I myself would not buy anything, or if it comes to merchandise then I will rather create it on my own as "fan work". Believe it or not, some works require just basic printing for being a "merchandise". You can order a tee shirt with your fave print at a printing workshop. You can do so with copy books, pens/pencils, playing card sets, bags, wallets.... whatever needs basic 2D printing. Recently, 3D printing is starting going to the masses. Therefore, if you have a 3D model of that girl that appears sometimes when you play osu!, you would be able to definitely print it on a 3D printer, or for some experts - make an action figurine or a doll. There can be 3D printing workshops too.
there's is nothing listed that I'd really like to buy. the problem is I don't really like the pink osu! aesthetic or think it'd really suit anywhere in my house. maybe if it had a blacker version.
the only thing I'd thing's I might be interested in are a good mug for coffee, maybe a poster, or some stickers to put on my computer. I'd might buy a figurine, except I don't feel like Pippi is a relevant mascot for what osu! is about TBH. I feel like someone like this would be more fitting.
