Bethesda Game Studios did not develop Brink, Demon's Forge, or Rage. The publishing branch of Bethesda pulblished these games, but they were all developed by different studios (Splash Damage, InXile, and id, respectively). Bethesda the developers (who have
only made the Elder Scrolls series and Fallout 3) had next to nothing to do with any of those games, so it really makes no sense that you'd base your opinion of them on any of those games.
