So to follow up on this earlier news, insiders have been coming out saying that these smaller cartridges are indeed gonna be a thing. How much this curbs GKCs remains to be seen.
I wanna have hope we could eventually get non GKC reissues of games, because supposedly there were Switch 1 games that did start out as Code In a Box before getting cartridge releases (having trouble finding which ones though), but unfortunately vice versa with Octopath Traveler, Nier Automata, and Mario + Rabbids Sparks of Hope.
Also, I think it's possible that this is another avenue of technology that AI has been f-ing up, considering RAM prices, GPUs and other stuff I'm probably missing have been getting messed up by AI. :x
