Idk if its making a "comeback" but it sure has been getting a spike in players recently (mainly due to the older people coming back to play). I think that when we were kids (like in 2013) minecraft was the game to play, while kids now a days play fortnite because its so popular with younger kids.
Minecraft comes and goes. When it does come, it’s fun. The game can’t really get old to a point where it “die”. You could always come back to it for a little.
