It's just one great game. JO's far from being one of the best games. First, it lacks scope. Second, nothing about it is really new except for the excellent saber combat system. Third, JO doesn't and won't have any influence on future FPS, let alone the games industry.
TWO supposedly revolutionary games are coming this year. Look out for The Elder Scrolls III: Morrowind (RPG) and Republic: The Revolution (RTS). The former's arriving in stores within a few weeks.
