One of the best games this generation and quickly became one of my favourite games of all time.
Brings back that old school difficulty and makes you feel awarded for getting good.
Unfortunately the PC port is not perfect, if you have the patience it can be quickly fixed with a mod created by Durante.
It is also highly recommended that you use an Xbox 360 controller to play this game but there is also mods that greatly improve kb+m.

If you are willing to add a mod or two you can experience one of the greatest games in recent times.
