Will the game need or has to stay with the same System Requirements when the game opens? Im still planning on upgrading my PC to Win8/Win10 (depends on my budget) But what worries me is that maybe there will be incompatibility issues when I do so. And also, will Win8/win10 run the game?
– Replies from the said OS and their experience to the game is muc more appreciated 
I don’t think there requirement will change once the game goes live (unless they put lots of lemonade in graphics). For the compatibility, it had no issues with Windows 8 or 10 so far, in fact, it can even run on Windows XP.
I’m on Win10 and it work fine so don’t worry about it, just meet the required hardware and install the necessary software (VC runtimes and DirectX 10).
Alright, thanks for responding to this post guys. And have a great day 
windows 10 works fine and if you bought windows 8 you should be more concerned with killing your self then playing this game. Windows 8 is ■■■■ use 7 or 10.
