3DS considered retro? I still remember my beloved Pokemon Black & White (Zekrom) DSi over 10 years ago. The design of it isamazing even if it is a subtle Reshiram & Zekrom glossy printing that was on the backplate of the DSi. I still have it, but the battery is basically shot.
Pokemon Black & White being one of my favourite Pokemon games of all time, I got the Black version because I like Reshiram more, brother got White for Zekrom naturally. Prior to that, I had a regular black DS that I played Pokemon Diamond on, brother got Pearl.
