Depending on the purchase price, the sales prices then also differ. The digital variant is also configured as a direct third-party offer. Here we only sell the corresponding code and have no verified information on the required storage space. According to non-binding internet research and information at https://www.nintendo.com/store..., it should be around 7.4 GB.
Yes, you can. However, you need a Nintendo Switch Online membership.
This is subject to a fee. There are 2 types: individual membership and family membership.
This membership can be tested for 7 days (which I would do to test whether the interaction between the Switch and the online connection works properly).
The prices can be found on the Nintendo website.
I hope this information helps.
Have fun
The language only refers to the packaging, the game should run in any language on the Switch.
It says on the back of the box that the software is available in any language.
You only need the subscription to play online. Offline, you don't need a subscription. You can play with four people on the TV/monitor. Or eight if each has a console and game.
I asked myself the same question and then bought the DE, FR, IT, EN, ES version because it is cheaper than the DE version. As expected, it works perfectly in German. No idea why there are different prices. Above all, the one with more languages should actually be more expensive...
The game can be started in English if you change the system language of your Switch to English or to another language (works with virtually any game) if there is no in-game language selection.
We purchase the item from different suppliers at different prices, which has a corresponding effect on the sales price. In this case, you can simply order the cheaper variant.
