[SIZE=10pt]I visit TamaTown V4 daily. It isn't hard to log in or out of, it's bright and cheerful, it's a lot more interactive, and there's plenty to do. Two features that I like a lot are the ability to earn points, and the password list at the end. If I don't have time to enter all the passwords, I'll screenie the list and enter them later.[/SIZE]
Its only weakness, which isn't much at all, is that some of the text from TamaTown V3 are still there. For example, one of the games, after you win it, says something like "you could use a mic like this." Unlike the V3 TamaTown, none of the games currently give out souvenirs, only points.
