More important is 
how you really feel about Father Satan and the Gods, 
what you think of them, 
how you relate to them. It is possible to play such games, considering it a common entertainment, and be a 
devoted Satanist, 
Warrior, 
meditate, do 
Military Rituals, and you can not play them, despising them, but do nothing for the 
Demons, your 
Race and your own 
Soul and to be just a mouthpiece, always criticizing but not doing damn thing.
Satan and the Gods will not judge, 
curse or 
resent the way you spend your free time: lying on the couch and reading a book or watching a movie. There is a Jewish agenda in almost everything in the movie, game and music industry, it's no surprise. 
No person in their right mind would censure you for what movies you watch or what games you play. It doesn't make sense. 
Your feelings, 
your morals, 
your actions define your Being. If you are 
honest and 
selfless, 
responsible and 
courageous with the Gods, and you prove it by your actions, then you have nothing to worry about. Even if you like to play something like this or even watch horror movies with a questionable, 
from the Satanic point of view, plot and concept, what is important is not this, but another thing: that which must never be forgotten — 
the Truth, 
Satan, 
the Way of Sat-ya. What is important is who you define yourself to be on this Path and who you really are to the Gods and Satan. Your hobbies, pastimes and other mundane aspects do little to define your 
Essence as a descendant of Satan. As long as your hobbies do not take you away from the main thing (
Spirituality and Power Meditations in particular), it is acceptable. 
It is likely that later, with experience, your 
Mind will reject all such things, as your 
Soul will want to be focused on what will keep it on the 
Higher Astral Vibrations. This will happen, but it does not mean that such pastimes make you an enemy of Satan or that you thereby behave sacrilegiously. There are truly sacrilegious acts unforgivable to Father Satan and his Demons, and I believe you can guess at them. Such acts are undeniable in their odiousness, and they are clearly not computer games with fictional characters flickering pixels on a screen. 
You may or may not give up such hobbies, if you like them and feel good about yourself. But I remind you, you should not give up the 
main thing and not forget about it, and I've already summarized above what it's all about.
I also suggest you read this Sermon as it also answers your question: 
"I Want To Do This...But The Jews..." - STOP THIS: WAKING YOU UP.
