It was a gaming team that plays some kind of action game and they meet eachother as the movie goes on , then make a team and participate in a tournament for that game . Which they end up winning with a last minute save .
Does someone know the name of this one?
“Best Player” (2011)?
No its not this one unfortunately.
“Noobz” (2012)?
Or another guess, maybe
“Good Game: The Beginning” (2018), original title: “Iyi Oyun”?
Wasn’t this one either . As far as I remember it didn’t had the word “game” in its title.
What about “Noobz” (see above)?
Nope 
unfortunatly.
was it in english? what kind of video game?
Sounds like ‘The Wizard’ from 1989.
Nope . The movie im saying is newer
check this list, especially “ehero”
Just going to throw an obvious guess out there, Ready Player One (2018)
I dont believe I saw it there but there were some nice recommendations I could watch
Nope but I have just watched it and it was nice
It was in english , it was a kind of action game . And I think it was a team death match kind . Which the main character’s girl teammate helps them win in the last game (the tiebreaker) with just a slight shot .
