I think people hate on it because it just kinda seems like a cash grab that has little to nothing to do with the game Minecraft lol
It may also have to do with the fact that the kids who grew up playing Minecraft when it came out 13 years ago are all jaded adults now?
I can't really say for sure... I was 30 when Minecraft came out and never really understood it's appeal in the first place lol I think I'm too old to have an opinion about it ๐คทโโ๏ธ
I spent a couple of hours trying it out once and couldn't really get into it. I'm glad your relative is enjoying it though!
