There are some games that I just dont seem to want to play during light. Hell there some things I dont want to do during the day. Some games are just perfect for playing in the dark according for ambience and atmospheric music sound and graphics. The games topic and plot just fit being played all by your self in the blackness of your confined room,and arent nearly as fun or not quite impactful. That doesnt mean its a bad game though. These games are mostly survival horror and fps(first person shooters). Here are some of my favorite alone dark games. Eternal darkness: not only creepy as hell but a great story line, a good morbid story line like that is also a good basis for playing in the dark. Like legacy of kain series. Blood omen 1 and 2 are some bloody @#$% and SO love it. Silent hill series. RE4 . Doom 3. The suffering. Haunting grounds,one of the most perverted sick games ever. Area 51 is a pretty good game to play in the dark, sci fi shooter. I will also say Halo 2 because the game has good lighting effects. Hope there will be more in the future.
