Nintendo isn’t popular right now in Lemmy due to their hostility toward emulators. Recently Ryujinx was forced to shutdown, and browsing around in the other gaming communities, posts and comments about gamers no longer buying Nintendo are getting upvoted.
So I think moving forward you may be seeing lots of downvotes on any Nintendo post anyone makes, specifically from users that browse by All.
Edit: I also forgot about Horizon. Sony is in the hot seat as well with their forced PSN network login hostility for PC games. And quite recently, Sony removed the original Horizon Zero Dawn game from store fronts (apart from GOG) and are forcing customers to buy the Remastered game for more money and the forced PSN login. Gamers are outraged about a game from 2017 getting remastered along with the PSN network requirement, so anything about Horizon will also face lots of downvotes.
Don’t buy from them. They don’t seem vetted.
Here are alternative known good sellers that also offer great discounts:
There are others that are legitimate.
Avoid places like the site you listed, and also these ones especially:
If you buy from Eneba, G2A, Kinguin, etc. you may be fine. However, there’s risk that you may not be fine and have a key that was purchased via a scam or stolen credit card. Then that game which is linked to you can be deactivated from your Steam account, possible Steam account ban, etc. Don’t buy from them because you just don’t know where that key may have come from.
