High Score Girl

both are romance themed stories focusing on eccentric couples and their antics. 

Both has romance and school plot Both main heroine afraid and shy if want to closer with male lead Both heroine have Dandwre type 

It invloes guy who finds himself stuck with a odd kind of girl and his life was never the same again.  

Another vote for Chuunibyou... not quite the same, but def warrants a rec IMO 

Both series are focused on growing romantic relationships between somewhat socially inept pre-teen/teenaged protagonists (which makes for great moments of awkward humour). Well summarised as 'learning to love' in both situations young male protagonists, both lacking in average social graces, meet insular young girls who find kindred spirits in boys who share/understand their offbeat hobbies. With the undercurrent of both shows focusing on the change in perceptions of these female protagonists as they grow from annoyances to object of genuine affection to the male protagonists. The adage 'sharing is caring' comes home to roost in these shows, as romance blooms in shared worldviews of the main characters and the friends that surround them in their stories. read more 

Balancing out values. High Score Girl and Chuunibyou explain the balance between what is fun, and what is the reality. Both anime have MCs who try to uphold standards whilst fighting off that which doesn't follow those standards. In the case of Hi-Score, Oono is made to study and live a high-quality life despite her love for playing games. Chuunibyou is slightly different, as Yuuta wanting to live by a regular worth away from his chuunibyou activities. These MCs are dragged down by Haruo and Rikka respectively. Both anime are great rom-coms focusing on hobbies and being true to yourself in the face of those hobbies. 

both are focused on video game themed storytelling and also romance as well too. 

Both main heroine falling love with boys not popular Both same taking school settings Both male lead only obsession on game. 

The same romcom where it involves guy getting involve with a gaiming otaku girl, except in Gamers the guy's girl is a hot otaku gamer, while in HSG the guy is involved with an odd girl that doesn't even speaks.  

Both animes have problems with romance. A main part of the plot is gaming for both animes as well. They both include some sort of issue to do with relationships. 

-Both are a romance story about love blooming between two gamers. -Both main characters are unpopular boys. -Both are in a school setting. -Both include some type of issue with relationships.  

The romance between gamers in these two series are quite similar. Despite Gamers! taking a much more shorter approach pre-love relationship compared to High Score Girl, they both delve into how friendship could turn into love between acquaintances in gaming. These two series also feature a love triangle, with the main characters as very knowledgeable in their games. In High Score Girl, the era is set in the 90s, specifically the "golden age of arcade video games" (so expect many retro game references), while Gamers! is set in the present time. To add, both series like to exaggerate and emphasize on situations throughout the story, which makes scenes quite melodramatic - that may or may not influence one's enjoyment in the series. High Score Girl especially makes creative use of video characters as a way to express emotions. Also, expect the animation of High Score Girl to be mainly done with CGI. Though it does it fine, so for those who have experienced CGI anime should be somewhat comfortable with this. read more 

Both Reina and Akira are small, timid, girl who grows attached to main male characters after they begin talking to her.. both are Dandere & Emotionless Girls who don't talk much but deeply cares about their friends and hangs out with them after school.. 

Short girls that have trouble communicating, and a dude thats trying to figure out what they are thinking.  

both are focus on lowkey otakus and their hobbies as well as their misadventures. 

Both anime have a relationship between the two protagonists in each respective show. Wotakoi and High Score Girl has relationships between characters in which they spend time in doing what their common interests are. Also both Hirotaka and Haruo are both into games and they spend time with their other, playing games together. 

Both protagonists are playful boys who enjoy being around a specific girl 

Both center around romantic relationship between a girl and a stubborn boy. Takagi-san is more slice of life while High Score Girl has a gaming element and is in CG. 

the girl, Oono resembles komi a lot. you can see parts of tadano in the boy as well. it's not totally addicting to watch but it makes you decide to see it through the end haha it's good 

both have a main side character that doesnt talk! both have a good story and the characters are vell developed! both have silly scenes and enjoyable momments! 

Both have retro gaming references from games mostly in the 90's.  

Beautifully orchestrated coming of age x romance anime. Great at displaying the awkward but deep different ways in which a couple connect and more than that share in intimacy. Both of them with a good share of laughter. If you are looking for an anime that will leave you satisfied but with a little thread of the what if? then this two are a go to. 

This anime has a lot of similarities for example romance, comedy, drama, the tension, the build up, their sad, happy and wholesome moments, the main characters social status, the difficulty to express their feelings to each other, they share some similar personality traits, also they are in school although you don't see them that often in it. If you liked Kaguya-Sama give this anime a try I promise it's gonna deliver the feels. 

Well many things are different among these both, the main characters are widely different but when it comes to the relationship between the characters - there is an undeniable nostalgia. They kind of end up on similar positions on web of relationships. I might have been too cryptic but i was trying to avoid any kind of spoilers....just these shows a try. 

Both series include arcade game insight with varied levels of success. HSG goes more in-depth with the games shown in AGF.
