Bioshock is not a paragon.
Wrong.
Okay, what is it epitome of? FPS? there are better first person shooters. Graphics? nope. Story? this is its strongest point but no, there is better. control? It controls poorly as a shooter. Depth? still nope. Bioschock is overrated. It is a good BUT linear single player fps with gussied up inventory control.
Bioshock controls fine on the PC. The visuals are some of the artistic and abstract of any FPS out there. The depth is a perfect blend between exploration and a linear path with multiple ways of approaching a situation not to mention a simple, yet emotionally effective moral system. So you are WRONG. I can't think of one FPS after Bioshock that is anything like it in atmosphere, story, morality and depth, not to mention artistic achievement.
