I'm upset that my best friend didn't come to my game.
Why were you upset that they didn't come to watch your game?
I'm the quarterback of the football team and I wanted him to watch me play.
I'm sure you were disappointed that your friend didn't make it to watch your game. It's fine to feel that way, especially if your friend said that they would make it. Talk to your friend and tell him how important the game was to you.
I think I'll give him a torrent folder of the game for him to watch later. At least he can watch it that way.
Yeah sometimes a friend has other obligations which doesn't always necessarily mean he doesn't care. You are very nice to give him a way to watch it later, that shows you care about  him. I feel your pain otherwise however.
