I felt differently about them. The first game was great, but the second provides very little innovation and is only about 5 hours long. It all takes place in that one area, which was a little annoying to me. I enjoyed Army of Two more than this series because it was a bit more exciting with the aggro meter. The story for K&L 1 is really good, but the rest is average. K&L 2 is crappy.
K&L1 ran like garbage on the PC that I ran it on. I had to throw just about most of the settings down. I'm betting that also didn't help matters, either.
I liked both games - but I do prefer K&L2.
I'd like to see a K&L3 - but I doubt that's going to happen, since they're namely sticking w/ just Hitman now.
