Is it weird for a girl to play minecraft just wondring?

No.Gamers in general are about 50/50 male and female.Games aren't just for nerds anymore and they've never been just for boys.

Nope, everyone can play any game, it is just many girls simply don't want to, you will see some but men mostly out number them.

No of course not. It's not weird for girls to play video games. There are things far more important to worry about than a girl playing a game.
