Of course it is. This is the goty this year and it only costs $15 to try it out. If you don't like it then it's not a huge amount of money lost, or do a steam refund. This is a great game. There have been a few pc issues but none at the moment are game breaking.
Music aside, this is the best Hitman game ever made.
Nice. Is it true that this game has always online DRM? This is pretty much a deal breaker for me because I have a pretty inconsistent ISP.
