This might not be the most important game, or it could've been. But just the game that took you to that next level. First ever victory? first ever victory with a horrible team? first ranked victory? National Champ victory? first NT victory? Shoot...it might even be a loss. 

Mine was against then #9 Redland (a current rival), can't remember the season, at least 10 seasons ago. I was unranked, with possible RPI of a billion. First game of the season. I beat Redland in a convincing way, dominate. First win over a top ten team. I knew then that finally I could play with the big boys. 

I wouldn't mind seeing some of the craziest comebacks or box scores.
I have my share of plenty, but always get topped by other people's games. 

I don't remember pbps or even scores very well - I don't know why...cough...

But my favorite game is obviously my only NT win...we were undefeated champions I remember that coz I punkishly stated a thread the next season during non-con play about longest winning streaks. Think I got beat like game 8 or so to end the streak ...(we went on to lose once in conference play - probably to alblack56's Bowie St team - and our only other loss was in the NT championship game...)

Any of my championships!     

My favourite was the year we lost in the PT Championship Game. In the Semi-Final game, my star player hit a 3 pointer with only a few seconds left to send us to the championship.
