Well, most of the things that you wrote about DimiX3 are in Blade Runner. Let me elaborate:
1) Black People
Sadik is black, though mot the main character but hes one of the important characters in the game.
Lucy shes a child, you can`t play with her but you can control how she reacts later on, based on the path you take in the game.
During your investigation, you will have to go to 2 Nightclubs to investigate.
Well, technically there isn`t a war one earth but there is conflict between humans and replicants.
Theres some drama in the game. Like when Steele died in last part of the game. Or life on earth where replicants aren`t allowed, and you have to retire them, well you can choose not too.
Theres comedy in the game also but not in FMV.
Well none that i can think of that are in the game.
Don`t need em. Basically you just shoot replicants
Lol, i feel like i`m promoting the game. I guess Blade Runner is one of those adventures it`s hard to come by.
