I bought John Woo Presents Stranglehold and Kane and Lynch Dead Men for PC together, so I'll do them both.
I would give stranglehold a 9. Yes it's outdated, yes it's at first a little wonky (until you turn down the mouse sensitivity, then the aiming is fine) but once you get used to it you're slaughtering chinese triad henchmen in a super stylish manner in absolutely no time whilst riding down rails and rolling accross the room at full speed on a cart. The game's dialogue also has an unintentionally funny aspect to it due to the heavy cantonese accent of Chow Yun Fat, which makes quite a few lines that otherwise wouldn't stand out memorable and funny. It's not a terribly challenging game mentally, it's often more about finding the most awesome way to put a bullet through somebody's skull. Get your energy up to full and you can pull off a room clearing roflcopter ripped right out of hard boiled. In otherwords, it's damned fun if you just go along for the ride.
Kane and Lynch gets a 9 also. Basically just think Hitman reworked into a combat focused 3rd person shooter which manages to be just as dark without you busting up child prostitution rings by killing a world famous opra singer. It works, alot, and the game stays fun throughout. The box talks about a crew based combat system but you won't wind up telling them to do much, they really are just there to heal you and to act as an ammo resevoir. Some odd placement of checkpoints is also a problem, having had to kill off the same light tanks before getting killed by the same helicopter ad nausium. The game in general is alot of fun, with the story somehow making a cop killing mercenary and a psychopath who tends to black out and kill the collateral seem somewhat sympathetic. Also, a good buy even on the PC, as opposed to the 360, on whic I had initially rented it.
