Ok, let's break down what exactly you're getting in this deal. you get a completely new game, a sequel to a classic class-based multiplayer game, a classic FPS, plus its two continuations. That is indeed a deal, but where to start the review? Well, let's start at square one, Half-Life 2. It's the same game that many of us have come to love over the years, and is indeed the same one that won over 50 or so game of the year awards during the time of its release. There is nothing changed except for the control scheme on the 360, (which was actually a very smooth transition). It retains the same charm it had when many of us first played it and then some. The two episodes really aren't any different, either. They both retain the same story and charm of the first game and build upon it and add to the suspense of Half-Life 2. If you haven't played HL2 at least once through before, you are going to need to before delving into the two episodes, and they will need to be played in sequence for best effect. All the weapons are satisfying to use and beyond that make a really pleasant experience for those playing, but let's move to another part of the game.
Portal. Yes, it seems like it might be lame, but it is incredibly fun, even if it is very short. The game itself shouldn't take much more than about 2 hours to beat on the first go round, (unless you just get really stumped on the puzzles it provides), but there is still alot more fun to be had after the first run through. It provides a series of much more challenging versions of some of the maps and even some challenges such as beat the map with as few steps or portals as possible.
And then there is Team Fortress 2. This is the lone multiplayer section of the package and is where a lot of the replayability come into play. it can provide hours upon hours of intense team heavy action and then some along with hours of frustration. A must play at least once, which simply won't be enough after you had a taste.
