Shangri-La Frontier: Kusoge Hunter, Kamige ni Idoman to su

Sung & Sunraku fight tough monsters to level up in a similar game fashion setup, both are fun action packed series with various entertaining fights against a variety of foes to get through. 

SLF heavily features trash games but is more action/adventury in genre while Full Dive is primarily set in a trash game and is comedic. They also both have certified banger OPs. 

Main characters both plays the game in unconventional ways and unlock random skills in the game that turn out to be super powerful. More goofy and chill version of Shangri-la 

They both have with someone playing an MMORPG game from the beginning with op skills at gaming. The worlds give off similar vibes although Quanzhi Gaoshou is more focused on esports  

- Both are vrmmo game based anime. - Both the MCs stand out for their playstyle and are smart with it. 

Both have the MC constantly face and struggle with "impossible" scenarios but will make it through the end.  

First of all, both anime share a common theme, and that theme is video games. Both anime have action, adventure and fantasy genres, and both main characters are high school VRMMO players. Compared to the Sword Art Online anime, SLF's plot is a bit more conventional, but it's also quite unusual. If you have watched SAO and liked it, SLF is the anime for you, but if you liked SLF, I recommend SAO. Finally, I would like to add that when I think about what SLF has that SAO doesn't have, I think of comedy and more action. 

- Both anime have skill based system and strategy based approach. - The fights in both anime are great and very well animated. - MCs in both the anime are not spineless and are smart.
