I have a v4.5 and a famitama. my famitama is pretty much the same thing as the v5 but I chose the v4.5 because it was my first! (well my v2 was my first but it's a long story)
My first one was a Tamagotchi v.3 but then I got a v.4 which i'm playing now, 2 v5's 2 v.6 and a tamagotchi plus color. the v.5 and v.6 i gave it to my friends i just have the v.4 and the tmgc+c and my mom had threw out the v.3 when I ws little.
I have a Autumn Leaves V4.5, Frogs V3, Baby Blue V1, Sunflowers V4, Cotton Candy V5, Fish Tank V5, Red Piano V6 (music star). And an Japanese Angelgotchi, Japanese Morino, and Japanese P1 on their way! I'm so excited! :mimitchi:
