I'd say if you're keen on trying these out, either pick up Re;Birth 1 when it comes out (in, like, two/three days) or go with Victory. The original is easily the most hilarious in terms of dialogue, but it's a poor man's Trinity Universe in terms of gameplay. It's slow, clunky, repetitive, and not really much fun. Mk.II has a much improved battle system, but the humour falls flat...at least, it did for me. I don't find pedophilia or tentacle/slime rape that funny myself, and the CPU candidates lack the charisma of their big sisters. Although the Conquest Ending was surprisingly awesome. But Victory has the best gameplay of the series and a fairly good story; it's the best one to start with. Not sure about the idol game...I've only played it for about ten minutes.

But I love this series. It makes a mockery of the industry, and considering how pathetic the industry is these days, it's all the more awesome for it. The voice acting isn't unbearable, the gameplay has only improved with each instalment, and the constant references to video games and anime makes the dialogue a laugh even if the story is run-of-the-mill bullcrap. I'm actually really glad its been so successful considering how bad the first game was. Definitely looking forward to the PS4 version.
