River City Girls is very good, but also very hard. I haven't beaten it yet. I enjoyed Streets of Rage 4 more as it was more approachable for me. And I had so much fun playing it with my brother Jeff. We would gang up on bad guys and 'baby duck' them. That's a phrase we came up with, and if you want an idea what it means, watch the 'baby duck' episode of Regular Show.
Aside from the orignal GBA game, Shantae and the Pirate's Curse is my favorite. I just reviewed Shantae and the Seven Sirens and it's a lot like Pirate's Curse, just a little bit easier. Not that I'm complaining about that.
