I enjoyed this game a lot, and I think if I ever plan on revisiting the original Half-Life, it will be through this. It's a more streamlined version of a classic updated to make each environment more distinct than the uniform feeling of the labs in the original. I would have rated this higher, but by the time I got to Xen, I was ready for the game to ramp up to a conclusion that took too long to come. Xen was full of cool ideas, but it almost felt like I finished the game when I jumped through the portal, and then still had to play a second game to get to the ending.
