I had to google the Dead Sea Effect: it means that when a workplace has a bad culture, the most skilled and ambitious workers are first to leave and those who have a habit to do the minimum will remain.
Anyway, I’d say this effect is weaker in this situation, because many workers are there truly to serve their country, not merely as “generic workers”. They might feel that they have something important to contribute to the society, which means there’s an actual chance for even some of the best to return.
These ones:
Kerbal Space Program
Morphblade
Dicey Dungeons
Fallout 3
Endless Sky
/usr/games/sol
(Plus on my phone Feudal Tactics and Shattered Pixel Dungeon)
