Been checking out this season's shows, it's not looking too bad.
Shoukako no Altair is similar to Arslan Senki.
Isekai Shokudou is a slice of life show about a restaurant / cooking, but it's like Gate as well. The restaurant is on a dimensional faultline.
Made in Abyss - kid friendly (no fanservice) adventure show with an interesting premise.
Princess Principal - what t.f. is this? It's a steampunk alt-history spy thriller, but with girls. Although it's got a subdued color palette, and gritty elements to it. It's a weird mix.
Vatican Kiseki Chousakan - a show about catholic priests who investigate murders and "miracles".
Ballroom e Youkoso - aimless kid takes up ballroom dancing.
Keppeki Danshi! Aoyama-kun - sports comedy about a soccer player with OCD / germophobia.
18if - weird show about people trapped in dreams. Episodes vary from cute to gory as fuck.
Centaur no Nayami - slice of life about a centaur girl at school.
Knight's & Magic - magic-powered "gundams" in a fantasy setting. It's been pretty fun so far.
Nana Maru San Batsu - anime about going in tv-show style quizzes.
Dive!! - for people who liked Free! now there's Dive!! with two exclamation points. It sounds like they're cashing in, except the light novel of Dive!! ran from 2000 - 2002.
Saiyuki Reload Blast - it's sort of like monkey / journey to the west, but with chainsmoking gunslingers instead of priests.
There are a couple of decent romcom ones too,
Koi to Uso is about a future Japan where the government mandates who you have to marry to boost the population growth, which ... isn't really all that far-fetched to imagine, given Japanese culture. first episode was pretty good, second one was so-so. Might become more haremy or fanservicy.
Konbini Kareshi - shoujo romcom one, but there are at least two potential couples here, might be one that shifts the focus around rather than on a single couple.
Sure, not all of those shows are great, but ... there's definitely tons of variety this season. I still have a few more I have'nt checked out too.
