EnTama is a whole lot better than V3 (Ok, I cannot say that, because i dont have a V3), but I assure you EnTama can do much more, is more 'logical', and is nicely presented.
They only cost around 19$ or was it € in Japan.
However in online shops the price is increased.
Entamas have four main families:
-Mamezoku
-Memezoku
-Kuchizoku
-Secret Family
They have many items, many aniamtions, and over 50 characters. Their characters are gender based, and they dont have training as such, they have GUT points, which enables them to boost intelligence, style and kindness, which decides what teacher they get after kindergarten, and then decides which job they must get.
They also receive newspaper and mail, have new games, more connection options, cool designs, characters, nice random animations, up to 99,999 points, connectivity with Kakeibo and MUCH more!
