I don't have a v. 4 but I do have a v. 4.5, and I like it. The v. 4.5 involves your tama going to school, then getting a job. It also involves some very interesting characters. One of my tamas turned into a tea-pot and another became a drum! You also get mail, and a mail icon will flash if you get mail. The v. 4.5 has a shop like the v. 3, and sells various articles at certain times of the day. The basic foods are very much the same with both v. 3 and v. 4.5, but one snack item difference is an orange with the v. 4.5, as my v. 3 had an apple. In short, the v. 4.5 can be compared with a v. 3, except for different games and characters, plus the additions of going to school and getting mail. Hope this will help.
