I got this game on my xbox 360 and had an absolute blast playing it. Only downside I can remember is the skill system that can make enemies tanky if you don't level your attack skills correctly. That and the horse armor dlc. But the best part of the PC version is the amazing mods the community have made that can change the game into whatever you want.
Like others have said the game is a masterclass in every aspect I can think of. Story gets you hooked, art is spot on, and combat is in that sweet spot between tactical and run'n'gunning. It's got puzzles, secrets, and a awesome soundtrack that never gets old even when you are stuck on one of the those puzzles. I absolutely loved the hub style levels where you basically switch maps but can go back and forth at any time and it saves everything you do. They even loop in on eachother sometimes and it creates this open world feel. The characters look and sound amazing with allied NPC's that can take hits while dishing out pure destruction and every weapon is viable from start to finish. Hedon is going down as one of my favorites of all time and I am looking forward to replaying it later. Plus I can't wait for part three whenever it comes out.
