The first game we checked out was Half-Life 2, which is essentially the same game that was released for the PC almost two years ago. The only difference, aside from the fact that you'll be playing with an Xbox 360 controller instead of a mouse and keyboard, is that the Xbox 360 version looks better. That's right, the Xbox 360 version of Half-Life 2 boasts visual enhancements that are available only in the subsequent episodic content on the PC, so regardless of how powerful your PC setup is, the Xbox 360 game will look better. To illustrate this point, we were shown a sequence in which you're riding through storm drains on an ATV and being hounded by an enemy helicopter--the lighting and particle effects were noticeably superior to those on the PC, and the water in the storm drain boasted a great reflection of the aforementioned enemy as it flew overhead. As impressive as that was, Valve's focus for X06 was clearly on Portal, so that's the game that we spent the bulk of our meeting checking out.
