Ohmigosh, what the heck is wrong with the V5? The instructions are very clear, and it's very easy to take care of. I mean, compared to other tamagotchis, you can leave it alone for hours and it won't die! It will only have, what, two messes? There are only a few empty hearts, and they're very easy to take care of and very easy to understand.
I think it's one of the best versions BanDai has ever made. But that's just me. I don't understand why everyone's bashing it ^_^
By the way, you can raise 1-3 tamas. That's why it's called a Familitchi. You can raise a family. I think it's cool 'cause you can raise different families, there are cool new games, new characters, and you can even get pets! There's the Dating Show in place for the Matchmaker so you won't have to worry about missing Matchmaking times, and like I mentioned before, it's very easy to take care of.
