Depends on the game.
I echo the other poster who said that as you get older, it gets less exciting.
But sometimes it's fun. My wife's dad has a box at the Astros (used to have Rangers and Texans box, too) and the parking is right up front next to the stadium, so that is fun - mostly for the box and the food and the fact that it's an easy good time.
Driving and parking is a B, so for special games (like the Big 12 championship a couple years ago), we just hired a limo to go to JerryWorld (Cowboys Stadium). That made it more fun, too.
But overall, 60 inches of HD and my own bathroom are usually better.
