呢個世界有樣嘢叫Uncanny Valley,如果一樣物件太過類似一個人,但又未去到一個地步人類望落去果陣會覺得自然既,好大機會會令人憎恨(i.e. 喪屍)
模擬市民二既人仔某程度跌左落去呢個Uncanny Valley,只喺因為果陣既Engine未夠先進,但喺果陣TS2既玩家喺成熟既人,佢地知道呢個喺創世大作,所以佢地接受左
去到TS3,個Game Engine已經進步不少,已經有能力將人仔從Uncanny Valley中打救出來,所以咪比TS2更加成功
模擬市民4既畫質跌入左Uncanny Valley,我個人覺得好核突,不過人人對Uncanny Valley既定義不同,或者會有眼殘人士覺得WOW The Sims 4既畫質實在太好 lol

The Sims 2:

面容,髮型線條生硬,而且動作不太自然,皮膚顏色因為燈光問題未得自然
但作為第一代有樣出既The Sims,個Engine唔夠Sophisticated可以接受

線條質素有所改善,而且動作表情開始傾向自然
