I’m liking it a lot. I’ve never finished Bioshock, but I’ve played a few hours of it, so it may not be a fair comparison, but the environment feels bigger and more convoluted, everything is less linear. It’s more similar to Prey than Bioshock.
Also, the progression of the player is based on gadgets and weapons, there are no powers to level up by using points.
And with Baldur’s Gate I’m playing a thief which a master on almost every skill, but not the best in combat jajajaja.
