Beyond a doubt, it's this PC game ! Took a couple of months to win the war ! Super hard and realistic !
Hardest videogame you have played?
Pong...the only video game I've ever played.
One of the most difficult games for me was Donkey Kong Country for Super Nintendo. I've played it many many times, but, I've only beaten it once!
Majora's Mask :/ I get lost and find myself running around aimlessly.
Hitchiker's Guide to the Galaxy ... On the old C-64.
Game was entirely text based, no graphics ... And you had to type the commands exactly right or they wouldn't work. Even with the "walkthroughs" that existed at the time, I never made it off the alien ship before I got so frustrated I quit.
Splinter black list
Ninja Gaiden.
