Maybe its just me but a lot of posts i see are really similar , most of the times they have only super popular games , some well known console variants ( mostly orange or black ones).
I think GameCube collecting is getting really stale compared to other consoles ( im also feep into N64 collecting wich have the same issue but less than GameCube ).
I also interested on Xbox and Ps2 and they are a bit more diverse than GameCube, PS2 owners loves obscure games too.
I think some people who made theses posts are just collecting for clout fame wich explains why they don't have games that are a bit more obscure ( even rare ones who are less known ) and might be way louder that standard collectors.
