That's what I mean though. If it's a complete game on a USB drive and doesn't require anything but the system/handheld/computer to run, then it doesn't need the internet. I meant an actual game, complete package. If it has any online vs, then let it be just a thing where you just log in with your own account. The entire game should be on the physical flash drive.
I understand what you mean and I also don't think USB stick idea is fundamentally nonsense, in a way it's "cool" in its own way and all but we still have disc technology at home lol. Well, these days people don't see a need to have disc drive anymore due to how internet is convenient but USB is still a common thing at least which why your idea makes sense more.
However when we think about real life aspect of the situation the number 1 "bad idea" is USB stick costs more than disc. This is why PlayStation using disc technology for example.
Then a person may question "why Nintendo doesn't use USB technology?". Well in a way we can simply say for them USB would increase the costs too lol.
Another "bad idea" issue is USB sticks are not durable. Not so common but there is always a risk that when you buy an USB stick it may doesn't work because during the transport USB stick was damaged due to too much shaking and all. Relatively even disc technology is way more durable. Another thing is over time USB stick stops working because laws of physics makes it degrade. Relatively disc technology is still durable on that too.
Yet, it's still not a bad idea to sell the game in a custom cool USB stick ideas as people here already pointed them out. But I would prefer to put my game into a disc instead because I'm stingy lolol.
However why I would use USB stick for a video game I developed:
Imagine a video game that require you to plug a particular USB stick just so you can load additional content the game requires to make some part of the game function similar to the amiibo idea. In a capitalist POV imagine people buy USB sticks that contains "characters" so to be able to use that character you gotta plug the USB to make the game load the data of the character. It would work in a turn-based kind of game. Then it would require its own special USB hub that can visually look like something out of the video game itself and thus you can break 4th wall in a good way like characters are "aware" they came from a "magical stick" and constantly talk to "players" by looking at camera by saying "thanks for summoning me, I know we can win this battle" and there can be certain dynamic between how X character saying the player that the player better summon partner of X character to fight better and constantly complains during the fight that player doesn't summon the partner. Thus it would make people wanna buy additional characters to complete the full group of characters that works better together!!!! lolol
Why people would wanna buy such USB sticks? When the USB stick looks like the character it contains it makes the USB a collectable item that's even cool to display. So the idea is BS which I personally wouldn't bother due to how money waster BS is it, but I know how it would be a "craze" at least in Japan lolol. It would make Pokemon logic matter IMO because what you collect is physically exists in real world and therefore people would form emotional connection to the characters they bought so we can also even sell "toy home" to contain these USB sticks by making it seem like characters' "living" inside of a house so it would make the whole situation so kawaii lolol.
