By far, the v1 is easiest to care for. Not too needy, the games aren't too long because you don't have to play them all the way through and there are only a handful of characters.
Versions 3 and higher have long games so you're gonna have to play through them. Once I wasn't bothered to work down my v4's weight, and when I finally thought I should work down its weight, it took half an hour! Think of what I could have been doing in that time!
