A question I've always had

"I have" sounds better.

There is something ion my mind these days, and I hope you guys can resolve it or maybe give an opinion about it.

"On my mind" sounds better in English, this is typically what would be spoken.

I have loved videogames since I was a child, I spendplay like thirdree time of the day playings every day with friends and having fun, although, I only play multiplayer games, because I think the best part of games is interacting with other people around the world and having different experiences.

"I have" must become past tense, as you "have loved" them since childhood. The revised sentence structure in the second sentence sounds better in English, although difficult to explain why. The rest is solid.

I mean, we usually meet knew people that doesn´t taln't speak your language, and it is fun because you try to communicate with them and understand what they are saying, so I think it is a good way to practice and meeting k new people that maybe can help you to improve.

"New" would be correct in this scenario as "knew" is the past tense of the verb "to know". "Speak" sounds better in this context. "Don't" is the correction contraction in this case. "Meet" sounds better here.

I'm also asking that because you know, many people say that videogames isare a waste of time or that you need to find a better hobbiey, but if what I'm saying is true, it would mean that games are probably one of the most usefull hobbies.

A different conjugation of the verb "to be" is required after videogames because they are plural. Hobby is spelled incorrectly. Useful is also spelled incorrectly.

Better as two sentences.

Do you guys think that playing multiplayer games can help to improve your English skills?

Some might say not to use "to" after help. Don't listen to them. It is optional, though, to use "to."
