Have you watched much of anything before? Likes? Dislikes?

My absolute favorite has always been Samarai Champloo. Same creator, also fantastic Coyboy Bebop.

Others I enjoyed:
Mob Psycho 100 & One Punch Man (same creator behind both)
Berserk (I've only seen the 3 movies for Golden Age on Netflix)
Attack on Titan / Shingeki no Kyojin
Trigun (I loved the original, but the recent remake was decent)
Dorohedoro (Incomplete, not sure if getting 2nd season)
Deathnote
Fullmetal Alchemist

If you want something to laugh at check out Grand Blue

Something to laugh at but it is an isekai The Eminence in Shadow or KONOSUBA

Or an SOL to laugh at BOCCHI THE ROCK!

• ODDTAXI (absolutely amazing)
• Madoka Magica (watch until ep 3 at least)
• Land of the Lustrous (very different animation style)
• Vinland Saga (great story)
• Your Name. (great romance)
• Baccano! (very interesting style of storytelling. The characters feel like something you'd see in a theatre)
• Dorohedoro (weird, but interesting)
• Dororo (just two good friends adventuring)
• Made in Abyss (gets good, but really takes those 13 episodes for that)

Patlabor, specifically "Patlabor ON TELEVISION" and "Patlabor New Files" (sometimes called New OVA) are takes place in a very comfy near-future environment and is about a group of policemembers who are under the division for dealing with any mech incidents, meaning giant robot fights will happen in a very down-to-earth setting

I also recommend the movies if you enjoy the GITS movie as it's the same director and he likes exploring a various amount of social commentary, from criticism of institutional inefficiency to existential reflections, (just dont watch the 3rd movie, it has nothing to do with anyone who made the original Patlabor)

There's also the original Patlabor OVA, but I personally didn't enjoy that nearly as much as the tv anime, and some of the characters act a little different, so it might be jarring if you watch that before the tv anime despite it being chronologically made first

Ghost in the Shell and Serial Experiments Lain are classics you can't go wrong with.

Fullmetal Alchemist: Brotherhood

Made in Abyss

Seishun Buta Yarou wa Bunny Girl Senpai no Yume wo Minai

Steins;Gate

Has anyone recommended Gundam yet? No? Good, I'm recommending Gundam.
Now, the whole thing might confuse you, and there are a ton of separate Gundam shows each one in it's own continuity. So, to make things simple, I'm going to just suggest two of them. The currently airing Gundam: Witch From Mercury, and the classic that started everything, Mobile Suit Gundam.
The 3 compilation movies of the classic Gundam are on the Gundam.info Youtube channel for free right now, by the way! There's several other shows in that channel and you might even be able to watch G-Witch depending on your location.
