Sadly majority of videogames totally childish, stupid and tasteless. Hopefully a create this topic for help to you find real gems of gamedev.
I begin my list by games developed in Russia by K-D Lab.
1. Vangers - world (worlds) after fall of Human specie. Not to naive anthropocentrism (heroes of this game even not belongs to humanoids), tottally alien lifecycles and culture of OUR descendants. Enjoy to bright future, pal.

2. Perimeter - Humanity (in Soviet style) colonize Eye of Terror and Warp (it's just allegory for better understanding). Unique gameplay, unique setting (it's not vulgar Western sci-fi about Space Roman's, it's more like Strugatsky-style sci-fi), hostile aggresive environment and godlike proud Humans (who are doomed - this game is prequel of Vangers).
