A good open world game that has detailed environment and can be explored every corner? Maybe some game I've been unheard of

For a game that I think needs no introduction but I know there are some of you who would skeptical about it even though it has so much hype built around it but I'm here to tell you that this game is a wonderful game that I honestly recommend to all those who are looking to get into battle royale games the gameplay is so much different from all the other battle royale games I've played . I can honestly say that pubg is the king of all battle royale games 🎮👌 and it offers things that games like free fire just luck like for example the graphic are magnificent and that just adds to the awesome story line

This is about a rhythm music game. This game was in beta back in 2021(most probably). It had 3 levels only. I unfortunately don't remember anything about it. It wasn't a popular game especially because it was in beta. It's probably a Chinese developed game but had English interface. There was an anime girl mascot. This game is an android/iOS game and was available on taptap. One of the level was chronostasis by 黒皇帝. That's all I remember.
