but at a glance

You must have missed this part. I'm well aware that Blue Protocol and Genshin Impact are very different, BUT AT A GLANCE, meaning only saw a few seconds of a trailer or some banner ads or something similar, they do look similar. It's funny you bring up BotW, since many called Genshin a BotW ripoff, despite them not having much in common outside of being open world and same art style, BUT AT A GLANCE, they do look very similar. Anyone who looks into these games for more than 30 seconds should be able to see they're quite different, but most will only be exposed to a few seconds of marketing, if anything, unless they're actively looking for more info.
