Earlier this week, PC Gamer reported 231,593 players Skyrim players as opposed to 78,161 for Modern Warfare 3. It seems this trend is continuing.
This is quite a difference in numbers between the two games. It would be interesting to hear how the two games compared from a sales perspective on Steam, although Activision says that Modern Warfare 3 has broken records from a retail perspective.
