We just played our first complete game, first quest of the base game with no expansion stuff. With three heroes and of course one overlord, it took us about six hours (though that included a smoke break). The overlord player was kind of bored, as the quest was very straightforward. He also had a hard time of it, as we had a ton of conquest tokens at the end (13, I think) and only lost any at all because of a stupid move early on when we heroes didn't know what was going on. One hero accumulated four or five armor and a shield and never took damage all game. With the Acrobat ability, I was able to run from town to a glyph, over two pits and two manticores, and shoot the boss three times in a row to kill him without the boss ever doing anything.
We all greatly enjoyed it and I've been eyeing second edition because I always wanted to own a copy of the game for myself. I know no one knows how second edition will compare, but just speaking in terms of first edition, how much will the experience of the base game vary from quest 1? Are there shorter quests, or can you expect game time to be reduced significantly with experience? Will the quests get more interesting for the keeper? And can I assume that it will get to be a more balanced game later on where the heroes will have a harder time of it?
None of these concerns are dealbreakers either way, but it would be nice to know. I don't mind the occasional six-hour game a couple times a year, but that game time is a bit prohibitive if we ever want to do a campaign with an expansion or second edition.
