My cousins would be babysat by my mom and before that our aunt babysat me and my sister so we're very close, and I recall every other day doing this. XD I was usually Pikachu, Mudkip, or Eevee, one cousin was Machop, Squirtle, Turtwig, or Riolu/Lucario. One of them didn't like to play as much and my sister refused to aknowledge me as her starter. :T Soemtiems, all four of us were Minun, Plusle, Pichu, and a made up one like them, mostly because of the Destiny Deoxys(i think) Minun/Plusle. We made up a couple of them too.
At my dad's house, we had a different group of cousins that was a lot bugger. There were two boys older than me, one girl older than me, two girls sloghtly younger than me, and I think there was another baby but I'm not sure. I haven't seen them in forever, but we used to get together in one of the elder boys' contry home and play outside in the dirt and grass, we prefered Pokemon stadium and other N64 games over playing for real though. Him saying my Eevee wasn't as good as Eevee could be because I only got him to lvl 25 really hurt too. :T
