A little too much trial and error, but worth the price.
Honestly, just like the last few Hitman games, there is a little bit too much of trial and error. Actually, that’s pretty much most of what you will probably do. Try this way, does not work. Try another way, works a little better, and so on. What does stand out though is the different ways that you can do things. You can't just go in blazing to accomplish your mission. There will be allot of disguises, as well as the option of "accidental" deaths. This definitely adds a little to the game, as you don't always have to just outright kill your target. A chandelier could fall, or possibly a crane with something in it. It gives a little more to the game.
Also new is notoriety system. After you complete your mission, depending if you are caught on camera, or happen to leave a witness, you will see what the media is saying about you in the local papers. Get a little bit too sloppy, and pretty soon crude sketches, followed eventually by accurate descriptions, or possibly pictures, will be in the paper. Then it takes money. Depending what you want to do, from just paying off a few people to getting a whole new identity can be bought.
I happen to own the 360 version, and the graphics on the game are absolutely great. I must admit as well, that the music goes along great with the game. You don't have to worry about allot of purchased music playing that will eventually get annoying. It's not my choice in music, but the soundtrack goes very well with the game. Overall, definitely worth playing.
