I love this game!  My son is 8 and he can play with no problem.  It has enough addition, subtraction and multiplication in there to count this as a math activity for this homeschooling family.  I agree with other reviews stating the game ends too soon, especially when you are only playing with two players.  You accumulate benefits for each of the buildings you purchase and the game is supposed to be over when someone has purchased their 4th building.  We have played past that by a bit before deciding to be done just because it was getting late, but I could see 6 or 8 buildings be a good limit for 2 players for sure, probably good for 4 players as well.  It's a fun game with great artwork and pretty relaxed play, I enjoy playing it in the evening before bed.  There are some great youtube videos explaining gameplay if it's your first time playing, but the instructions are well done and it's pretty easy to pick up.
