The description on Board Game Geek is as follows:
This is a negotiation game in the truest sense of the word. In it, players acquire ownership of sections of city blocks then place tiles, representing businesses, onto the block-sections. At the end of each turn, each tile you've laid gives you some sort of payout, but completed businesses (formed of three to six connected tiles of the same type) pay quite a bit better. All these resources are dealt to the players randomly, however, so players must trade to get matching businesses and adjacent locations.
Oddly, there isn't much to add on this. It's a fun game for our group because we have players who love a good trade game and interact well together. I guess if you are playing with a new group, this might not be the best game. People either need to be somewhat experienced gamers or comfortable with one another to really get the full flavor of this game. If you have sensitive gamers in the group who are prone to get their feelings hurt if someone else tries to win, they might not like this game or you when the dust settles. I think this is an excellent game and not at all difficult to learn. Looks good, feels good.
