Players are leaving this game because it's only about making money, and they have no intention of supporting a corporation that does nothing but profits.
Secondly, many players have quit because American players are ruining the servers with their alliances, which only boost the tank levels of their friends. The rest of the non-American players can't get better because their egos won't allow it.
The only good times for Steel Legions were between 2012-2016—after that, the game died, and now it's even worse. Only Americans play, while everyone else has left, and rightly so. Players know that if the developers don’t care about them, then they shouldn’t support the game financially either. The company should fund its own project instead of relying on free support from ignored players.
I recommend the same to all of you. The old players will return—I’m in contact with them, and they’re willing to come back. All it takes is the will to update the game and add new content. But because of the foolish American players, the game remains in its current state—they can’t take a break for a year and stop donating.
