I just re-read the comments above, and found something rather... odd.
For me, Talisman is one of the most streamlined adventure game ever. That's why I can enjoy the story, the funny stuff. On your turn, you only roll a die, and read the cards. There's card play with spells, but for most of the turns, you are just doing the same thing.
Just compare it to other similar games. Sometimes those games challenge you even to just move, crowd the tables with multiple decks of encounters, item levels, no meticulous calculations about your resources... you just roll with it.
And that's exactly why it works as an adventure game for me.

Star Fleet Battles ain't exactly streamlined, but it sure is better than Days of our Lives. A game like that could go the distance in an environment where there isn't 100,000 on-demand data streams competing for your attention. It's length could be a positive feature because by the end of Summer you start getting pretty bored.
Used to play AH Civilization back then, It could have been a little shorter, since it was 6-7 hours with a meal break somewhere in there. It wouldn't have been the same if it was 2 hours long, and that wasn't something that we would've thought was even possible. Ah, good times.
As for Days of Our Lives, when I was going to college I used to watch it with my grandma. General Hospital was the big thing then, but I had to be different. About 6 months of soap operas and you can pretty much call them done.
