Some people are just complete assholes, While Roblox, Fortnite, and other Multiplayer games actually have a set lifespan(once servers shut down for good those games are dead forever) the games you play have an offline mode that lasts forever, while I enjoy Fortnite, I played Roblox before(not really that interesting I mainly played other people's Game Modes) I'm not going to act like they are the best games ever, you do you and enjoy your games, I am 20 and I went through the same shit you are going through at your age, best to do is just ignore them because they are idiots who have never played a great campaign mode, fun fact back in High School I loved Nintendo, and everyone else did not care at all, well when Mario Kart Tour launched everyone was playing it, While I already knew I'd have fun with it, so best thing to do kid is have your own idea of fun and to ignore idiots who are just being assholes for absolutely no reason, they just don't know what a true Gamer is
