An incredible but technically broken game
What do you say when a game in released in such a buggy state that it not only runs pathetically on very high end computers, its actually impossible to complete because of a game breaking bug that remains for over an year before a path is officially released (and that patch coincidentally fixes almost none of the major performance problems). The pain may be traced back to an absolutely broken hl2 engine, an early buggy version that is light years away from teh final one. its a pity that such a fantastic game was butchered so badly as to be unplayable.
