I've been playing 7 Wonders a lot with my friends ever since I got introduced to it from my last workplace. A big plus about the game is that it doesn't take too long to set up or play. This makes it a great game to play when people want to try out multiple boardgames in a session, rather than play a marathon session of Arkham Horror. :) The drawback is that there is so much to explain at first and so many symbols to learn that to the new player it seems a lot to take in at once. However, it usually only takes 1 game to get people up to speed - the concepts are really simple especially if you've played other strategy games before.I do have to admit though, it does get repetitive if you play it too much, which was why I got the Cities expansion recently. The addition of some new cards with cool properties adds some more depth to your strategy as well as a bit more of a random element. I still think that the game probably plays best with 4 or 5 people, as the chances of you knowing what your opponents have in their hands as well as having a card come back into your hand are both lowered. As a result, decisions have a much higher importance and urgency.
Maybe I'll invest in some sleeves for the cards - the cards at my old workplace appeared to wear out quite easily and I've started seeing some slight damage to the edges of the cards in my set. :(
