Here's a quick comparison:
- B&W took over a week to finish, but PM2 took 2 nights
- I would never play B&W again (replay value: -1) but I can play PM2 however many more times I want, and I can start from middle by saved games and end up with a different ending
- In B&W you constantly get annoying by the retarded motherfucking villagers, whereas in PM2 you get to see your daughter naked. Ok so in Creature Isle expansion your creature will get to have sex with Eve, but peh, that was boring as fuck
- In B&W you can't exactly "be good or be evil" because you'll quickly realise that the game is havily biased towards the "good" side and by being evil there's no way to win the game, you'll either lose faith/villagers, or you just get zilch for doing the silver story scrolls. In PM2, you can grow your daughter to be a prostitute, or a nun, or queen of darkness, or petty thief, or a princess, or ...
