It's not like optical where a game can be any size up to the maximum capacity of the disc and you can even add a second disc at low cost if you need to increase storage. Cartridge games will always be under pressure to be smaller because that is always cheaper. Macronix do a huge range of sizes. I'm sure games like bomberman may actually be very small on Switch and Zelda probably represents the maximum capacity for the moment which I think is 16GB capacity although in the past some games were more heavily compressed on cartridge for 3DS than digital downloads because they had to be shoe-horned into a set cartridge size with Nintendo preferring to increase loading times rather than waste space on the cartridge. 3DS games range from 128MB to 4GB in size. In the UK it looks like 8GB or 16GB Nintendo games may have a £60 retail price but sub 8GB games may be at £50. However in the past often the smaller cartridges from third parties had a high price so those could be £60 over here as well. No one is expecting 1-2 switch to be anything other than a tiny cartridge. So lets not pretend cartridge prices and capacity are not going to be a huge issue for the Switch. Even producing a small simple 128MB game on Switch on cartridge is going to be a lot more expensive than an optical disc containing 25GB or 50GB of content.
3DS game sizes here;
oh of course, optical will still be cheaper to produce even though price is a lot lower for solid state storage now, but the cart has it's advantages and that's why I'm going physical with Nintendo this time instead of digital like my other collections.
1.) potentially longer lasting.
2.) no installation required and seek time is good out the box, outside of maybe some patches, it's drop and go.
3.)micro SD slot will only be used for saves and some patches, so you don't have to spend too much on extra storage in the long run.
4.) Amazon Prime pre-order for cheaper prices.
5.) better used game market, harder to get fucked up copies.
6.) easier to store, I'm just gonna dump shit in a box or bag and not have to worry about things getting scratched.
7.) I'm sure there are more but, fuck 1-2 Switch, I'll take it for free for the sake of free shit and still not play it.
