If you like SAO you there's a possibility you could like
Solo Leveling. I've read the novel and it was really nice. The art of this one is just perf <3. The webtoon is still incomplete.

But yes, speaking of SAO it was indeed unfortunate that the MC (main character) was invalid. I haven't watched it yet, I was saddened when I heard he was not like he used to be. Season 2 was really great for me. It really resonated with me especially with those last episodes, I was dealing with the loss of a loved one at that time and that kind of gave me closure(?) and understanding. Just... Anyway, that was personal but I've seen a lot of hate on SAO lately and I was happy that there are some people who came out here and said it was really nice <3 Cause it was for me.
So, OP (Original poster) If you haven't watched No Game, No Life. Anime. It's really nice. And Overlord. Anime. Same as SAO's plot to some extent but the art is not as colorful as SAO but it's nice too.
Minna do u know manga as good as sword art online? (๑•ㅂ•)و✧
