The game is very good, a lot of fun, quick graphics even on older machines (the game is for sure less demanding than FEAR or Riddick), long story, nice locations, great physics. Just a classic game if you like FP shooters. I love the game especially for its open spaces and views. Just gorgeous!
The Holiday collection goes with some more titles but only Half Life 2 is actually on the DVD, the rest has to be downloaded by a special program called Steam. This is a platform developed by Valve (the Half Life producer). What it means is that you need an Internet connection to be able to get all these additional games. It is not a very big issue if you have a fast connection at home, but in my case the download was very low so I had to wait a few days before I could even try these games! And even Half Life 2, which is on the DVD, had to be first updated before I could run it. And if your connection is sometimes down the Steam is starting very very long. It finally allows you to play without the constant Internet connection but the whole system is far from being user friendly. There is actually a god support at Valve websites and you can buy other games using the same Steam platform, so it is not totally bad, but you have to consider your Internet connection before buying this pack.
