Probably not a standard (for the question I mean) but Super Punch Out for SNES.
I played it all the time, I remember playing it that hour before I was forced off to school, one of those games that you just wanted a taste to get your day started right. I got so good at it that it was at a point where I was trying to shave off time by hundredths of a second to get the best time and a better score. I remember lamenting over the lack of two-player competitive, as I felt at the time that I would destroy anyone, which is stupid to think about now since all I did was gradually memorize the AI sequences and figure out how to counter them for the swiftest victory.
I make sure at least one month out of the year I have my SNES plugged in and available full time, SPO always has a spot reserved (along with FFIV, FFVI, CT, SoM, SMW, Mario Kart and NBA Jam TE, that's actually a pretty ambitious month if you want to complete all the RPGs.)
Also, I'd be remiss if I didn't mention Zombies Ate My Neighbors. I could never get to the end of that endurance test of a game, but it was always fun trying.
