Neptunia I guess, though it's more tongue in cheek than Senran Kagura by a country mile...SK kind of feels like they throw the silly stuff in after, Neptunia is the reverse. Love the characters, design, humor. There's also a Senran Kagura not-quite-crossover character--Marvelous, who is a representation of...Marvelous, dresses like, and has palette swaps of, Senran Kagura characters and is a Ninja.
I also have a Super Sonico PS3 game but it's half VN and thus pretty hard/frustrating to play. The VN stuff is unfailable though, and the rest is dress up/photography which is pretty fun. It's obviously low-budget though, her boobs/clothes have assorted clipping issues.
Disagree. Story is not so important here, personalities are, and Versus does a great job of expressing those, in addition to far superior performance, gameplay, graphics, fanservice...just, everything. I would really recommend starting with Shinovi Versus unless you really like okay-tier story and can tolerate an incredible amount of highly repetitive and not very good gameplay. I got two chapters in and didn't see a bit of story I'd consider redeeming.
