A terribly beat up v3- Yellow with stars (not sure if that's the design name). I dropped it on a flight of stairs, and then someone stepped on it. It survived that, but once it's practically unusable by now. The buttons are almost completely unresponsive. I still hold onto it because it was my very first Tama, easily from 5+ years ago. Good times...
Another v3; light blue. It's in a much better condition, thankfully, but I haven't used it in a long time.
v4; light green with flowers. Sliiiiiightly worn? It's fairly old, but still usable. I loved it when I first got it, since it had more features than the v3.
v4.5; tiger stripes.
v5; white with the house. Ah, I love the v5 a lot. I would always fret when the paint or the screen got scratched, I wanted this one to look perfect. Got it about 2-3 years ago, off Amazon.
v5.5; light blue with a purple star. I got it before my v5, thinking they would be the same. I don't have anything against the v5.5, I just happen to like the v5 more. I played with it a lot when I first got it.
Music Star; red with some sort of guitar? I couldn't stand it at first because the buttons were so unresponsive. I also didn't like that you had to start feeding it food that wasn't default after it turned into a teen, I could never get enough money to keep it alive. I also kept failing the pro debut. Sigh. I still like it, just... a little less than the other versions.
I also have 2 Tama-Go's; one black, and one white. I got the white one when they first showed up on Amazon, it was before my local Toys'R'Us opened. I really like the graphics-- it's not color, but it's definitely something! The figures are also really nice; I've got the Chamametchi, Memetchi, Kuchipatchi, and Violetchi ones, besides the 2 default ones. Does anyone know where you can get the Shimashimatchi one (he's my favorite, but I didn't get one when they first came out)? I've seen one on Amazon, but it comes with a set of the other 5, I don't know if I want to buy all of them.
