I've never had much chance to try economic games like this, but they seem fascinating. I am a huge fan of board games, but when it comes down to it, I've never really had the time or a sizeable group of friends equally devoted to such games, and it bums me out. I would love to try out 7 Wonders and give you a report, if I ever find an opportunity.
And you might be interested in knowing that my wife and I have a history of playing Sorry! Still a great game.
