Games in Manga/wha/hua

Okay other than reading I like playing games so whenever I read stories that are game based especially BLs that have the couple meeting through a game like netkqma punch, this guy is that guy or my guildmate next door where they not just focus on the romance but also introduce the game and it’s mechanics I just thought they’re lit games

I also noticed this a lot in manwhas that the mechanics usually goes like this:
-customizable character
-have to choose a certain starter role or occupation so later on they can transform into an evolve(?) version of said starter role
-have guild
-guild fights
-PvP
Maybe they’re just made up by the authors but still does anyone that have read those and knows games that have similar game mechanics or if you were to reccomend any game?
