What do you think of Eevee as a starter?
I actually liked the thought of Eevee as a starter, given all the Pokemon it can evolve into and it's a popular Pokemon, not to mention it's the rival's starter in Yellow. It would have been better if the necessary stones or the Moss/Ice Rock were available earlier. I do agree with Alex that I was a bit disappointed that I'd find myself stuck with an Eevee for a while in some circumstances.
As for Shiny Eeveelutions, I love Shiny Umbreon the best cos of the blue rings. I was disappointed with Glaceon and Leafeon's Shiny colors since they have not much color difference at all. They're basically just lighter, brighter versions of the normal colors.
