I just played a game of Oh Hell with Tal where, instead of bidding sequentially, we bid simultaneously. It definitely made the bidding a little wilder. I suspect that the variant shines with more players in the game.
Trying variant was a suggested by Adrian Morgan, a fellow blogger who has designed a number of interesting looking games for use with standard components. Check his blog for details.
Next Gen reports that the price of video games is now averaging $60 a pop. Considering that these keep only one person happy at a time and eventually get solved, board games for $10 to $40 sound like a bargain.
