Summary: ...so you can start on something else, I have played some games recently that have been advertised as the best graphics and the best A.I. etc. This game has good graphics and the A.I. is good, the game however is not that good, its... a bit anoying. Once you actually start playing (after the long 'cartoon') it feels like your looking for the start of the game, and a few levels later you still feel at the back of your mind "is this ever going to get anywhere?
Summary: I was impressed by the graphical detail in the characters' facial expressions and in the scenery of the game world Valve have created, especially the strange part alien, part machine dropships that look like some kind of weird flying crab. The physics engine is impressive and the gravity gun makes the most of this, allowing you to manipulate objects to use as bridges, stepping-stones or projectiles that can be fired on your enemies.
