This needs going in the OP, the thread is full of people acting like this is being released around the worldIt won't be able to run and you won't even be able purchase it, I don't think a lot of people are understanding what this is exactly. This isn't something you can just go and download from the eShop anywhere in the world with a Japanese account, this isn't a thing being downloaded to your Switch at all. You need to be in the vicinity of a cloud service station, there's several in Japan so it'll probably get a wide range in several key cities. In Japan (and Korea) there's an idea of gaming cafes, where you pay the cafe to use a computer for an extended period while there, this is sorta' an extension of that but for more on-the-go in Japanese life, these stations don't just solely provide RE7 either or just Switch stuff, they provide a number of services. Essentially from the cloud service stations the game is being streamed to your Switch. It has Switch controls, such as Gyro aiming is confirmed, but it's not actually on your Switch, and you won't be able to buy it unless you're within working range of the area covered to stream it. It's essentially streaming a video feed to you and taking in your input controls, but you need to be within range of the stations to even buy it.
I keep telling people this isn't a replacement for a port, this isn't even really a port, it's a Japanese gaming thing which has existed for a bit and these things usually stay Japan exclusive due to it being a very different market, but I think people are getting the wrong idea and thinking this is some wi-fi only RE7 port where you need to always be connected to the internet. It's not the internet you need to be connected to essentially, you need to be connected to the cloud service stations, which only exist in Japan.
Theres no reason why this experiment means a proper version isn't in development as well
