I gave it a 7.. It is good but I am disappointed that we can not dive and explore under the water like we could in sims 3.
Also, my sim left her police officer career at level 5 because I think there is a glitch in it (she can't arrest suspects because the suspects are also police officers and the option to arrest is not there), she started the diving career at level 3 and for some reason or other, she can not advance even though she has been on excellent for sims days now.
I would like to have had hotels and more/bigger lots to build on as well as some new kinds of venues.
I do like it but I feel it could have been alot better and is a bit disappointing. I am only hoping the forthcoming magic one makes up for the short falls of Island Living.
