There's a game called "SeekL" which is very simmilar to this one!! That game actually made me obsessed with this kind of stuff. There's also "Killer Chat" where instead of hackers you got killers (don't know if you're into that but I am :^...) but the game really makes you feel like your talking with someone real and not playing a game!! Both are free and can be found on here. I really recommend checking them out !! :3 (sorry for any gammar mistakes, english is not my firts language ;-;)
