Maybe in the 80's: but AH has definitely moved towards the more accessible end of the board-game market.
I don't doubt that board games could be huge. Unfortunately, there haven't been many innovations in the mass market in the last few years. They concentrate too much on "Lord of the Rings Risk" and "Simpsons Clue" and "Star Wars Monopoly" They can only rehash that stuff so many times.
Sure, there are lots of things like the stuff you listed, but board-gaming really is in a renaissance right now.
There's been tons of new games released within the last few years that have totally won me over, and not all of them are "Euro-Games" either.
To name a few, try:
*Shadows Over Camelot
*Betrayal at House on the Hill
*Runebound (Soon to have a "Midnight" expansion!!!)
*Arkham Horror
*War of the Ring
Not to mention that I still play some older games, like "Acquire", "Fortress America", and "Axis and Allies".
And the good ol' standbys, like "Puerto Rico", "Carcassone", "Settler of Catan", etc.
And there's more stuff poised to come out soon...
They've already reprinted "Robob Rally" and "Great Dalmuti" and they're soon to be reprinting "Fury of Dracula" (YAY!!), and "Ra", and the new "Descent" looks pretty cool. AND there's another expansion for both the "Game of Thrones" boardgame, AND the "War of the Ring" boardgame.
So yeah, board-gaming is up there on my list of things to do, second only to D+D.
