I've gone to games since the 60s and came really, really close to not renewing this year. It's a combination of reasons, but the main one is the way Ohio State treats its football customers like they're in a prison camp. Once upon a time, you could go visit your friends in other areas of the stadium (after halftime, usually). You could bring a cookie into the stadium. (A security guard confiscated a chocolate-chip cookie from my purse two years ago. Seriously.) You could bring a bota bag in. You could tailgate without hiding what you were doing (always makes me feel like a teenager and my parents could be coming home early, so hide the stuff, man!). I am treated as if I was some sort of enemy. Now, of course, 9/11 changed a lot of things. However, since 9/11 I have been to many away games (Texas, Washington, and most of the B10 schools). Not one place does to their fans what Ohio State does to theirs. Every year they seem to come up with yet another rule or increase in cost to make it less and less pleasant to spend a Saturday afternoon there.
As far as cost, I contend that you can still take your family of four to a game for a reasonable price. You can't do it for a big game, but for your average Indiana game you can park, walk to the stadium, and wait until almost kickoff. The scalpers are practically giving those tickets away...and thatt's another reason I probably won't get tickets next year.
