One’s opportunities to be socialized do require parents understanding the important of playing with one’s friends. Like, it does help to be one of a four-guy team who plays competitive sports. It helps a hell of a lot for bonding.
At the age of 11, one doesn’t control one’s own access to opportunity. OP’s mom did him dirty.
If being unable to play FIFA is the single biggest problem in your life - your life has pretty much zero problems. It's not the mom's decision to buy a computer that screwed you over, bud - it's your attitude about life in general. Nobody owes you anything, you want a better life go out and earn it.
I don't think I've ever heard the words "nobody owes you anything" from somebody who was a good person. Or understood how a society works. Or cared about their impact on other people at all.
