On the heels of the announcement that Halo 2 has received a 9.7 from the Official Xbox Magazine, their highest ranking ever, comes word that PC Gamer has rated Half-Life 2 at 98%-- also that publication's respective highest ranking ever.

Of course, there's no real crossover here-- Halo 2 right now is only for the Xbox, and Half-Life 2 is only for the PC. But in the battle of blockbusters in digital entertainment this holiday season, these two giants are battling directly for attention, if not for customers.
