Apparently, the release date for "Halo 3: ODST" has been severely broken in many countries (enough to allow the game to chart).
Judging by position only, "Need For Speed: Shift" is doing way better than its predecessor. Releasing it earlier than last year, and as such avoiding direct confrontation with the others sales-monsters, is so far a good move.
