My introduction to the series not the greatest game ever but I enjoy it for what it is. I like moe, otaku pandering and humor, the premise of the video game console wars but with cute anime girls is pretty amusing. To my understanding Re;birth 1 is actually a fan favorite. But I don't really agree with that I like the later sequels a bit more. I still think it's a decent game that's worth trying if you find the cuteness of it appealing. Fan service wise I never quite understood why people take such offense to it in Neptunia. The games are rated T and the fan service is overall pretty mild and not as over the top as Senran Kagura. Personally I like most of the characters, Although ironically Neptune herself probably least favorite of the main 4. Noire, Vert and Blanc are likable though and I enjoy Compa and IF as well. The battle system is pretty mindless and overly grindy sometimes, but I find it pretty cathartic and relaxing and I like that it's like a hybrid of turn based and action rpg. Overall it's not the greatest game ever or anything but sometimes it's nice to enjoy an average low budget game such as this.
