Baldurs Gate. There is so much content. I’m 150 hours in the game, I play split screen coop with my wife. We each have our characters customized to how we like it. It’s AAA quality. Came at a AAA price, but it’s absolutely worth it.
And I say this as a FPS/simulation gamer. Totally different genre but they’ve made this game accessible to all. It’s the only game I’ve ever purchased at full price and my steam account is 12 years old.
