Gamers!, Net-juu no Susume Recommendations
Both are about gamers with a combination of romantic comedy.
Both include gaming/romance/misunderstandings (Gamers! has a lot more though)
Both tackles in the premise of the life of gamers. Net-juu is the grown-up version of Gamers!. Both have a likable romance going on (Well, Net-juu takes on romance is goddamn slow but still it takes it nonetheless). If Gamers! is all about a misunderstanding, then Net-juu is all about a coincidence.
Both series have MCs that the couples are gamers. The romance is similar as well as characters. The comedy is funny and hilarious. They also socialize in games and the real world.
