15 [Similar Anime] Like The King’s Avatar

This show continues the ongoing trend of video-game themed anime, but The King's Avatar goes about it in a mellowing slice of life style.

These feature skilled gamers in fantasy MMORPG settings. Though the plots differ considerably, there's no shortage of similarities in other regards such as the engaging action sequences, the very skilled and confident protagonists, and the cute female companions.

Both MCs are gamers in their real life and part of a guild, though only the protagonist of Quanzhi Gaoshou is a pro gamer.
In these MMO-RPG (Yggdrasil for Overlord and GLORY for Quanzhi) you can choose from a vast variety of classes in order to create your avatar.
Both MCs are overpowered and no one can defeat them; they can use unique skills and weapons and they are more experienced than everyone else.
Both anime's focus is on MC himself and fighting against other users (Quanzhi) and/or NPC (Overlord).

The main characters are both smart/strategic, very experienced, and are highly respected in their respective worlds. Other similarities include the use of gaming terms, guilds, and great action scenes. Quan Zhi's battles are far more intense, though.

Both have very clever main characters who love the thrill of the game and attract others to them. The worlds are very different but the ambition and spirit of the characters are similar.

Badass main character who's can be a prideful prick? Check.
Modern and Good Art? Check.
Action-packed fighting by main character who is a legend, but also "flawed"? Check.
Both MKnRand QZGS are fantasy/magic type animes that don't try to reinvent the wheel, but still remains refreshing and intriguing. While they are sort of directed to different audiences, both elicit either a love/hate response. The side characters are surprisingly memorable and different too. QZGS's beauty is the character development and unique stories while MKnR is all about "imperfection" not being an excuse for being OP, hence the huge class divider.

Quanzhi Gaoshou is perhaps the most popular Chinese anime at the moment, but Zhen Hun Jie (Rakshasa Street) is nowhere near that in popularity. However, they are the two highest rated Chinese anime on this site and deservedly so. Though I think that the plot and characters are more interesting and engaging in Zhen Hun Jie. Each episode is only 14 minutes on average which makes it an easy watch as well. I recommend checking it out if you're looking for Chinese anime to watch.

The main focus of Nanatsu no Taizai and Quanzhi Gaoshou is not the plot, nor is it even the characters. What both of these shows focus on is the spectacle. Nanatsu no Taizai throws together a world full of ridiculously strong creatures and characters and subsequently uses its story as an excuse to throw them against each other. Quanzhi Gaoshou uses its premise of professional MMO gaming to show off as many visually impressive action sequences as possible.

Tanya is young soldier who battles for Germans in WW. The nations war is similar with guilds. Tanya is apathetic equally as Quanzhi Gaoshou MC.

I am recommending this anime for the similar elements that both present, as the dungeons with various monsters to defeat, both animes have charismatic protagonists and that are progressing during the story goes on, the animation of Quanzhi Gaoshou is sensational, the battle scenes are beautiful, the two animes are very good, both from Dungeons to explore, guilds and cool characters.

They are both action-packed and focus on battles between characters with various abilities. While Quanzhi Gaoshou involve game characters with different classes and skillset, The Outcast involve characters with different supernatural abilities.
They both feature an amazing ensemble cast where the MC is surround by competent and charismatic supporting characters with unique personalities and backstories.

The MCs are gamers. They have their own place to play games. They know each other in real life so they formed a club.

Two series that focus on the world of their titles and their leading characters survive the hiccups that appear before them. Both series don't use an "arc" based formula that many manga and anime do but instead have multiple plots intertwined together to create a more complex narrative, that isn't always apparent but still compelling.

The feeling is similar. Both Sei and Ye Xiu are really passionate about games and battles. And you can feel their enjoyment of the game.

Well, at first glance this recommendation seems a little strange but it is not as farfetched as it might seems.
First of all in both anime special attention is given to the character and development, based on the personal life stories.
"Netojuu no Susume" does appear a little more Ladylike due to a female main character and involving a lot of emotions. However, in both anime the game play is not focused, but on the other hand the characterization based on interaction and the ongoing plot is done pretty well, without being too predictable.
To me these shows appear like representing two sides of the same coin. Both take look at the benefits and disadvantages of online games, on the one hand a pro-player who starts struggling his way back to the top and on the other hand a woman trying to re-discover the feeling for the beauty of life.
I enjoyed both shows.

Both involve players playing Multiplayer RPG kind of games where they are uber powerful.
In one game he is sacked from that game and must start anew and the other the game ends and he must start a new game.
