I've decided to not read light-novels which I've already read on their manga version (Mushou Tensei, Tate no Yuusha and Arifureta Shokugyou. Same with Mahouka, since I watched the anime, but tons of people have told me to read the LN so I'm reconsidering it... ), at least, until I've read several new ones! I'll mark Symphogear to watch it later! Never heard of it so I'll give it a try. I absolutely loved Clannad, Sakurasou, Little Buster and 3-gatsu no lion! Are you watching the second season, by the way? It's going really good so far, last episode made me smile a lot
For Visual-Novels, I can't say I'm an expert :'( I've only played a few, two of them: Yumemiru Kusuri and Katawa Shoujo.
I'll note the books too but I can't promise too much! Recently, I've been only reading LN and Mangas :'(
