I began Sunrider series with the Academy spin-off and it made me play all the other games too. Why so? Academy has its own problems with too long and routine simulator that makes people stop playing it before actual routes, but I actually liked it, that's quite relaxing. And ofc the main reason I became a huge fan was the novel part. Everything is drawn perfectly, my ideal drawing actually. Narrative and hentai are also perfectly matching together, everything stands on its place. Also music is something I'm in love is every Sunrider game. So it can be a bit boring in the beginning for somebody, but reaching your waifu's route makes you fall in love totally and play all the other games by Love in Space even if they are not such hentai.
Of course, the second work of Love In Space would have problems. Great, mostly perfect turn-based strategy has bugs because of the old RenPy, also balance is not perfect. But do I mind it replaying game many times? What is much more important for visual novel is the narrative (and some CGs ofc). Here is something Sunrider hit me right in my heart, it's not just about cute waifus, it's a huge space opera that made me laugh and cry. Also the Liberation Day has higher quality in everything, but it's really important to play the Mask of Arcadius first, so just try it, it's free and maybe you would be next to join our great community.
