I downloaded this over the weekend on the Xbox and I'm really enjoying it. I didn't appreciate that the H1 and H2 levels were also included initially (at least as far as I could see from the main menu) so I fired straight into the Hitman 3 levels. I've completed the training, Dubai and Dartmore levels. Currently in Berlin. I have found a few bugs though. In the Dubai and Dartmore levels, spiking two specific drinks consistently crashes the game
Very annoying. The always online thing is another annoyance.
I didn't particularly get into the previous Hitman games. I thoroughly enjoyed Absolution, even though I appreciate it was a big departure in terms of gameplay. I played a few levels in the other games here and there, but I guess back then (2002-2006) I wasn't into the puzzle aspect, and just ended up getting frustrated by treating it as a semi-action game. This version is fantastic though, so maybe the fact that I now appreciate there is no rush makes a difference.
The graphics are stunning too.
