This was pretty much my favorite game ever. You get to run around, hide in the shadows, pop out and execute a buncha guys in so many ways with stuff like plastic bags, glass shards, choke wire, machetes, baseball bats and stuff. It's the only game that really makes you feel like a ninja. other ninja games just have you out in the open in a hack-and-slash style. It's just awesome, you can cut off peoples heads and then throw them at other guys. If you like violence, the movie saw, hostel, etc. you'll like this (as long as you get the hang of it and don't get frustrated). I don't own it though. I wish it was for sale so I could buy it.
Back when Manhunt first came out, I gave it a rent and I got just to the part where you have to save your family members. I thought it was too difficult, so I returned it. But I began to think of renting it again, so I did. And I love it. This game is so awsome with everything it does, it's very intense. I just finished it a few hours ago, and I've got to say, it is nothing less than spectacular. I think the only complaint I have is that the executions get pretty repetitive rather quickly. But other than that, this game is definetely one of Rockstar's best.
