Metal Gear Solid 4|
Release Date: 2008
Release Date: 1997
This was Halo before there was Halo. Based off of the movie with the same name, Goldeneye was, and still is one of the greatest first person shooters. Despite the crappy AI and dated graphics, it remains one of my favorites. It is also proof that movie licensed games don't always suck.
Super Mario 64|
Release Date: 1996
Mario's first transition into 3D, and most would agree it's his best. Who could ever forget spinning Bowser by the tail for the first time? What made this game so great was the amount of variety. Lava worlds? Got 'em. Snow worlds? Got 'em. Sky worlds? Got 'em. Underwater? Nah...but they have those too.
Sonic the Hedgehog 3 & Knuckles|
Release Date: 1994
The Sonic the Hedgehog series had always been good up until this point, but this one was simply the best. It was actually 2 separate games, but it featured a unique, one-of-a-kind way of combining the 2 to make one gigantic adventure. In addition, it had the coolest levels, musical score, and of course, Super Saiya-err Hyper Sonic.
Release Date: 2004
Fable was great on so many levels because of the amount of customization. You could be a skinny, evil swordsman, slaughtering innocents and aiding bandits, follow the righteous path and be a buff ass mage, or many other things. What you did not only affected the story, but your appearance as well.
