I'm at some silly number of hours (12? 15?) on PC, and haven't even finished the prologue "mission" for Dexter, since I've been doing side missions and exploring. I've noticed many faults of the game (crappy driving AI, cowering citizen AI instead of running away, etc), and I agree that this is much more similar to Deus Ex (e.g., mankind divided) or the witcher than GTA. However, I haven't seen any game breaking bugs. I once saw my weapon glitch and be invisible .... until I changed weapons. I'm sure they exist, but I am having so much fun playing the game (even with potato graphics from a 4 year old card). I have hardly touched the plot, as I haven't even gotten to the events that were completely spoiled by the game's trailers, but I still feel like I'm exploring a living city.
