I have three

! Definitely one of my favorites (although I only have V2s, V3s, V4s and a game boy version and all are my favorites, all of them have so many cute characters!

).
Mimitchi's right, the glow in the dark ones REALLY glow well in the dark! It's not just a dim light that you can just barely tell is glowing, it's a very bright light for glow in the dark.
The point system is wonderful! If I know X character focuses on Q points then when it's a teen I play M game to get the points and then it will most likely evolve into the character I want or at least not evolve into the character I didn't want
