Stricktly ero-games: Fortune Arterial. It's sooo much superior than the lame anime version. It's a shame, really. Erika's path was awesome and cute. The true path + true end was quite conclusive even though it had for me as romance fan one huge flaw (which I won't say due to spoiler reasons).
Sharin no Kuni + Fandisk: The fandisk was quite epic. And Natsumi in SnK (1) is sooo adorable
Shuffle! Essence+: If only for the abosolute non-drama route of Kareha-senpai.
Majikoi: Kazuko >= Chris > Miyako = Yukie > Momoya, simply put. From the very little I've understood, I enjoyed it. Can't wait until the full translation patch will be out.
@Muv-Luv: The school life-comedy Muv-Luv was average. It was a shame that 90 % of Sumika and Meiya's routes were basically the same except for the choice selections. I don't care for the gloomier Muv-Luvs because I don't enjoy those settings.
