Any kind of game
EDIT: changed from suggested to mentioned and made the title more clear
This is a hard one because I generally try to play good games these days, and good games either get popularized through word of mouth or Youtubers make video essays about how they were misunderstood at the time. For me, this question is really asking “Hey what weird trash did you find back when you were 10 years old digging through the bargain bin for whatever you could trade two games you finished for.”
I think my big picks from the weird trash are The Urbz, which comes from back when they made Sims spinoff games instead of endless DLC, and Ty the Tasmanian Devil, which was a 3D platformer metroidvania that revolved around collecting increasingly elaborate boom-a-rangs. I definitely sunk the most hours into the Urbz, because nothing was more fun to a 10 year old than going around a virtual town flipping people off.
