Diablo. The second and third parts of Diablo, after so many years, still occupy places in all the top co-op games. Reasons for success: high replay value, balanced balance, exciting gameplay. Any fan of good action RPGs periodically wants to download one of the Diablo games, call friends and go to Sanctuary to deal with overzealous demons.
GenshinImpact. The iconic open-world RPG with gacha elements features a massive storyline and many characters to collect. The game can be played alone, but it is much more interesting here to team up with a partner and go to conquer dungeons full of monsters and adventures.
Destiny 2. Destiny 2 is a joint battle against alien invaders, accompanied by a story full of mysteries and a carefully crafted futuristic setting. The game takes not only addictive gameplay but also beautiful graphics that show amazing landscapes.
