Since start, lot of players have left the game because it lakes content (only 3 races).
Then SEGA / Relic say they won't release a new content (additional race) because steamcharts are too low...
=> Are you seeing the paradox ?
This is obvious that a new race like Chaos or Tyranids would boost steamcharts ! Come'on Relic / SEGA, propose us an payable dlc! Chaos daemon is already made in the campaign!
