Things always change, community see that. But for community isnt important what was here before 2 years or so.
Community see progress in last 6 months and compare it with another projects like 2077 and Requiem.
I know being a developer is harsh, everyone only critize you. Same being a GM. And after 2 years of steady work everyone will be tired.
So im saying, that there obviously isnt enough manpower.
If someone think that 3 devs can work on such project like 2238 steadily for 3 years and dont break, they are dreaming. They dont even get paid.
Problem of slowing down developement isnt in you devs, everyone gets naturaly tired after some time. Fresh blood is just needed.
Obviously if there can be projects like Requiem and 2077, there are skilled scripters which can be helpfull and maybe willing to help.
