I also wouldn't spend 2K on a game, but I love going to live sports events. NFL I've only been to two games (late 80's/early 90's) one was Denver in Cleveland the other was Chicago in Pittsburgh. Enjoyed both games, but the one thing you don't get from watching on TV is how truly impressive some players on in person. John Elway's arm strength is one of those things you just can't fully appreciate on TV. Been to tons of MLB and NHL games and there are some players you just can't appreciate fully in on TV. Grew up watching Mario Lemieux play both on TV and in person and he was so impressive in person. Benn to tons of auto races in person as well. One note is baseball is actually a more fun game to watch in person than it is on TV.
As for football I did stats for our college football broadcasts for 2 years (before doing side line reporting, while in college), and my stats were very, very close to the official stats. They were close enough our play-by-play guy was comfortable using mine on air. Now, I will say, working the game is very different from sitting in the stands and enjoying it.
Once we get moved to Durham, my husband gets his health under control, and we can safely go to games again, I'm looking forward to going to NHL games, college football and basketball game and some Durham Bulls games. The Durham Bulls are about the only minor league team I'm willing to go to games of. I grew up going to MLB games and minor league games just aren't the same.
