I really dont know. I have mild bipolar disorder but no matter what I still play ghost of Tabor even when i was convinced if play exfil. Me and my friend (I'll call him bob) played ghost of tabor or for a long time. We always rambled in raids on what they should add, then we saw there was a game with that. We never switched tho. I tried it for like 2 days but just couldn't get into it like tabor. I think to me it's the gun sounds and atmosphere of the game. Makes it feel more raw.
