Pros: Only the best sports game since checkers.
Cons: That everybody doesn't own this game.

I still remember my days as a lad. With shaking hands I pulled my Atari 2600 from its corrugated confines along with a shining new game. "Football", it was called. I could barely contain my adolescent glee as my father struggled to hook the game up to the television. I burst with anticipation as he fiddled with the cords. I stood with baited breath as he worked.
An hour later when he finally got the thing hooked up, I was practically wetting myself waiting to play this game. And finally, up it came. "Football" the screen read. I spent hours trying and trying and trying to figure out how to get that game to work. Which multi-colored rectangles were my team? Was that another player, or the ball? Who am I? Is this thing working? Yes, many questions filled my mind in my youth, but the greatness of the game remained. For years, no sports game could ever match the sheer joy that "Football" for the Atari brought to me.
And then it happened.
Into my life game NFL Blitz 2000, The 'no rules' version of football. "Pedestrian", I said to myself. "Certainly no football game could ever match the intensity of 'Football' for me old A-tari." Still, being short on a social life, I gave the game a rent.
My God.
The bone jarring hits! The flaming passes! The muscular kickers! The seamless animation! I was taken aback.
Today, NFL Blitz 2000 remains the cornerstone of my video game collection, the watermark to which all sports games must aspire. Blitz has everything:
1. Good control. The game is ridiculously easy to play. On offense, A jumps and B passes. On defense, A jumps and B tackles. Z is turbo. That's it! Get the timing down and you too can be a Blitz-master.
2. Incredible graphics. The players are all muscular and chiseled (yes, even the kickers), the animation is superb, and the environment has all the speed and fury of a real football game. True-to-form NFL uniforms are used, with all the details right down to the color of the stripes bordering the numbers.
3. Great sound. The theme song gets stuck in your head after a while. The players are hilarious as well as real-sounding. And for once the announcer has a respectable amount of catch-phrases, as opposed to simply "First down!" and "What a hit!"
Teams all have their strengths and weaknesses. Some teams are excellent passing, others are excellent running (not that you ever run in this game) and others still are excellent defensively. There are no "perfect" teams.
Finally, NFL Blitz takes all the "seriousness" out of football games. In football simulators like the infamous Maddden series, you can spend hours just trading players and never actually playing a game. In blitz, you go with the roster you have and pray it's enough.
Readers, NFL Blitz is the definitive sports game of the late 90s. Buy an N64 and Blitz and never buy another sports game as long as you live. Single person or multiplayer, simply no other game holds up.
