Wonderful! Let’s see… “What are ye selling/buying?” is a quote from the shady shop-owner in Resident Evil 4. Pyramid Head is from Silent Hill 2, of course. There’s a Tetris shirt and a few Miyamoto motifs and a few more Phoenix Wright quotes but I’m pulling a blank on the rest.
There’s two Rez t shirts (the guy bottom left, the guy in the center under tetris). There’s also two Shadow of the Colossus shirts, the “grab something hairy” ones that have the tattoo pattern on the breast pocket area.
“Stop, Sabre Time” is from the classic Ultimate (now RARE) game Sabre Wulf. Still a great game.
“Horisse” - the purple/blue big-eyed figure with wibbly legs - is Horace, start of shonky early 80’s UK computer games like “Horace goes Skiing” and “Horace and the Spiders”, which were crap even then.
