Crystal Dynamics studio head Darrell Gallagher today told a GDC panel that their Tomb Raider reboot had the "biggest opening" of any videogame so far this year, and that in selling 3.4 million units in a week, has set a franchise record. This is reported on GameSpot, where they also note Square Enix has stated the game has not met its sales targets, which raises the question of how they arrived at such lofty Crofty expectations.
