Genius thy name is Half-Life
The graphics are second to none on any console before the 360 even with the sometimes jagged frame rate.
Talking about the frame rate problems, it never interferes with the gameplay
which is superb in every aspect including the newest, the Gravity Gun.
This one weapon defines the games entire personality and distinguishes it from games such as Halo and the original Half-Life.
Sound is as good as the originals excellent sound design and the game is quite substantial, taking over 12 hours for a well practiced gamer to complete.
The lack of multiplayer is not as bad as has been made out as the single player game is enough fun on its own to merit a purchase in the same way that The Chronicles Of Riddick was.
