Elf wo Karu Mono-tachi surprised me a lot with modern isekai concept and really good humor while having next to zero ecchi despite the plot - felt like a firm masterpiece during watching .
Koukaku Kidoutai is the second genius masterpiece I can proclaim , plus this season sees the start of Neon Genesis Evangelion even though its first half was not outstanding
Since Maruko-chan can't participate in the contest due to absence of subbed episodes, there are no other masterpieces, and among others I favor Armitage III
Again no masterpieces. As of decent ones, I'd say that Taiho Shichau zo is the one I enjoyed the most even though it's just franchise setup with 4 episode OVA .
Don't know how to put it... but I gave away the first genius masterpiece score to Gunnm already. There's also one firm masterpiece Kyou kara Ore wa!! .
I failed to find something really good in Summer 1992 season, Kurenai no Buta is the best title among the decent ones, but I still don't consider it a masterpiece.
Yokoyama Mitsuteru Sangokushi is not as spectacular as Sangokushi movies, but I was interested in learning the roots of the story so much that I enjoyed it substantially nevertheless.
I can highlight two borderline masterpieces - Osu!! Karate-bu and Chibi Maruko-chan Movie with original work always taking precedence over recurring one of equal score.
