Each part of the metro is a masterpiece that can be dissected for hours and discussed on the various topics that they raise. 4a Games, like GSC, did something unique, so much so that only people living in the post-Soviet space can truly understand the meaning and be completely immersed in the universe of their games. For example, in the metro series you can often see the characteristic interior and exterior of buildings that have a scoop-like feel to them. Who else but post-Soviet citizens are destined to experience this whole picture for themselves.
Metro is my favorite series of games. From the setting to the gameplay. Personally, I saw for myself one single problem in this series. This is the player's shadow. The rest doesn't bother me much.
I hope that the new part will be as masterpiece as Exodus!!
