Really unfair and a d**k move not giving the people that funded the launch era of the game steam keys.
2 choices are hoping your early community will buy it again for more than double the price and them hating you
or
give out steam keys, keeping a nice community that plays and supports the game on an additional platform.
Promising you that most people that bought it here and supported it since launch will not buy it again for more than double the price.
