Not to say whether video games are halal or not. But people do waste an awful lot of times in front of their consoles and computers (espiecially children). You can put this time to good use by remembering Allah with His zikr. Or atleast take on some physical actvities to gain some health. Our Prophet Salallahu Alayhe Wasallam used to encourage his Companions (RA) to take on activities such are horse-riding, wrestling, archery, etc. He even used to encourage them and congratulate them upon attaining excellence in such actvities. So having a good time and enjoying a bit is not really prohibited. Just take up some useful and productive activities.
So please, think twice before suddenly passing verdicts such as "Yeh mulla baray hi vailay hain" waghera waghera. Waisay hi hamari qaum bari peeche reh gaee hai apni kahili aur susti ki waja say. Apnay time ka sahi istemaal karain.
