Bioshock 2 is often criticized for being "QOL Improvements: The Game", and where that's true, I think it's still a stellar sequel. Taking control of a Big Daddy is already an interesting premise held up by refinements made to the combat. Of the few things I can complain about, the underwater sections could've had a bit of combat, but they end up as segues into other levels with a bit of collecting. Bioshock 2 is a good play if you enjoyed the first game. Its improvements to combat, hacking, and the amount of tonic slots you're given to build up your character make it well worth the 10 hours.
