I played the Sims and The Sims 2 on PC years ago and when I bought my mac I had thought about The Sims 3 so I bought it. I enjoy the game very much, though there are some issues that prevent me from really enjoying it.
The game tends to take far too long to load. I have a Macbook Pro 9,2 and even with the upgraded 8GB ram and SSD it is just a bit laggy most of the time. I have to turn down the graphics settings to pretty much all minimal in order for smooth performance. I am not thrilled that the game is so limited in activities and there seems to be bugs that I can't yet pinpoint. I did purchase the Late Night Expansion Pack and while it is okay, it is definitely not what I hoped for when I purchased it. It provides some nice features of the game but I can't figure out how to go to a club or bar yet. And living in the big city is not as great as the promo makes it sound. It seems to take longer to get anywhere since you have to take a taxi to the subway then from the subway another taxi. Yes it's like real life for huge cities like NYC but no, this just isn't worth the price. I likely won't purchase other expansion packs until the prices drop significantly from where they are. I would love to have the Pets expansion pack and Generations but really, if the gameplay additions are the quantity and quality of Late Night, I won't be happy.
The default censor is annoying as it is gray and black with some clear in it and it just looks bad. They seriously could have made a nicer looking censor when the sims go to the bathroom, shower, etc.
