Personally, I was a big fan of Nintendo 64. It may not be as old as some other consoles (such as NES, SNES, Genesis, etc.), but it was released ten to fifteen years ago, which is still pretty old. If it isn't considered a classic yet, then it definitely should be. Anyway, I loved N64 because, at that time, this console arguably had the best graphics quality around. The only video game console that was ever able to compete against Nintendo 64 was PSOne, as it had a great selection of games—rest were almost hopeless. d:
One of my favorite games for N64 would have to be Mario Kart. My cousins used to come over at our house every weekend, and I used to spend countless amount of hours playing the game with them. We used to do coin runners and balloon battles, since we found them to be quite fun. We used to do some regular races as well every once in a while. Star Fox was also one my favorites. If I remember correctly, my highest score in this game was two-thousand seven hundred and fifty-eight. I always tried to reach three-thousand, but unfortunately, I was never able to. :( Other than these two, some of my other favorite games were F-Zero X, Super Smash Brothers, Super Mario 64, Kirby: The Crystal Shards, and Legend of Zelda: Ocarina of Time.
