Focus and Saber could have profited with SnowRunner to really push things further and do the right thing and start fresh but instead they chose the easy way out which was to reuse the large portion of the underlying code for the physic aspect and other function from Spintires and MudRunner which is really old and not really up to date which lead to having almost decade old issue resurfacing in that game.
SnowRunner is MudRunner with a fresh coat of paint with messy code integration underneath.
If you are still interested to buy that game you have to keep in mind that many bug remain and a large portion will not be fixed and you will have to fix some by yourself, so that game is best to be bought at low price in the five to ten dollar.
-Local coop is not supported unless you are using a VPN which is really mind-blowing.
-No offline mod, meaning you need to always be connected to internet if you want to play even if you are playing solo or you lose internet connection.
-Coop is not reliable you encounter lot of sync issue crash disconnect etc.
-Mod support is not reliable lot of save corruption can occur as well has other issue.
-Tool for mod creation are from an other era and lack many feature and some function have been also removed rendering integration of a model really time consuming compared to other game engine also they are riddled with bugs.
When it comes to making maps it even worst since some experimented people have lost hundred of hours of work when the game updated corrupting their files.
-Lack of proper quality check.
-Poor communication between Focus/saber and the community, and poor game support.
-Quantity over quality they release a lot of content but poorly finished, map with misplaced props, asset reuse is really high, vehicle animation can be really bad half finished, vehicle handling not even finished etc.
Aside from that great service from Cdkeys.
