Landmark computer games of the 20th and 21st centuries

[Lando]

Metal Gear solid (PSX) - Revolutionary game.
Tekken (PSX) - Best fighting game ever, with jaw-dropping visuals for the time.
Command and Conquer (PC) - More groundbreaking than Dune 2, imo.
Mario 64 (N64) - Best ever title available at a consoles launch.
Splinter Cell (XBox) - The best visuals I've ever seen in a console game.
Chicken Run (PSX) - Just because it was the first game I worked on and it felt good to see it in the shops

Yes but it doesnt have to be the first in the genre to be the best

I think C&C defined the RTS genre (more than Dune 2), Mario 64 defined the 3D platformer genre, it was truly innovative when it was released - nothing like it had been seen before.  Tekken defined the 3D fighting genre, even though it was a rip-off of Sega's virtua fighter, they improved upon it and made it better than the original, and now when people think "3D fighting game" they usually think of Tekken.  MGS and Splinter Cell are hard to categorize, they're more than just shooting games (Stealth'em-ups?) but I couldnt choose between the two.  MGS because it was the first, Splinter cell because it raised the bar.

You're right I did misunderstand completely, sorry
