SOMEONE BROKE THE THREEADD!!!!!!!!!!!!!!!!!!!!!!!
Anyway it's been a while since I've left some commentary so I'll add some now and from Top 20 onwards, I definitely will post them here.
22) Super Mario 64 (N64)
21) Call of Duty 4: Modern Warfare (PC)
Two Games that one could say are genre defining games of each of it's respective Generations and in fact, forever.
If you owned a N64 and did not own or play Super Mario 64, then there's something wrong. First 3D Platformer to ever be so successful and critically acclaimed. The sheer amount of fun you could get out of SM64 is unlimited. You could always go back to each world and replay the fun mini games, find the red coins, etc and so much more. Anyone could pick up the controller and join right into the fun and amazing world of Super Mario 64. A truly amazing Platformer and all die hard Platformer fans like myself would agree.
Call of Duty 4: Modern Warfare is the reason why CoD is the beast it is today. After a disappointing Call of Duty 3, I had my skeptics about CoD4, fearing that it would be crappy just like CoD3 but since it was a Modern game, I decided that it wouldn't hurt to play a Modern War game since I was bloody sick and tired of WWII Games period and my god I was so glad that I decided to play because it blew me away. The Single Player was engaging and very well paced. Accompanied by Solid Gameplay and intense action scenes, CoD4 blew away all my previous thoughts on CoD Games. The Multiplayer is simply brilliant and addictive, making players wanting to play more and more. CoD4 back in 2007 was the Ultimate FPS Package with a thrilling Single Player and exciting Multiplayer and is still is hailed as one of the great FPS Games ever.
