My 8yr old son is very controlling when playing video games and is an extremely sore loser.. It's making me not want to spend time with him playing video games anymore.

A quick example of this is him and I playing Super Smash Bros. Ultimate. He wants to spend forever nitpicking over maps and rule sets and characters and if he doesn't get to choose 100% of everything he'll whine the entire match, make snarky comments, quit the match to the main menu entirely if he's losing (even when we play on a team), and just generally make things less fun.. and it's just so tiring. It's like he just doesn't care about cooperating or compromising, despite understanding the concepts of both.I don't know where he's gotten this attitude from but he's always been like this over games and I've never worked out the right way to help him grow in a healthier direction. I've never put great importance on winning. I congratulate him on games well played if he loses and make sure I praise him if he does (rarely) lose gracefully. I don't gloat if I win. I ask him what's frustrating in hopes I can figure out something to do or say to help.. Nothing has worked. When he gets this way I immediately end game time which, obviously, causes a meltdown.I just.. I enjoy playing games a lot (especially with him!) and I'm a really chill person when it comes to anything competitive, but I'm raising a kid who is the type of gamer I dislike.. Anyone had any luck with this at all? via /r/Parenting http://bit.ly/2RQDPjv
