i have a list of anime that i plan to watch or have already watched, from the 90s to 2010s that are popular with otaku. there are a few i didn't include because i either watched and didn't like it, or don't think it'd be something i'd like. am i missing anything? anyone have any suggestions? i am open to stuff from the 2020s, i'm just not sure what's popular or even coming out these days that isn't mainstream since i haven't really been involved in the otaku/anime community in a long time (at least the ones who talk about newer stuff that's more niche or too "anime" for the average watcher. most of my friends like and talk about the more mainstream stuff (some aren't as mainstream but still have the feel of being so), and not saying that as a bad thing because some of them are good, but that's how i find out about newer anime and no one i know talks about anything that might go under the radar for the average modern anime watcher. i have one friend who likes some more kind of niche newer anime, but not really anime nerd kind of niche). there are other anime that aren't on here that i do like, but i don't feel like they fit on the list so i didn't include them. i'm also open to manga and VN/game suggestions, but i'm not going to make a list for those since the post would be too long.
