I was originally going to go with Black because I prefer Reshiram and like the color black over white. However, once I learned that Rufflet/Braviary were exclusive to White, I had to switch. Normally I choose my game based on the preferred legendary, but this time I picked because I simply adore Braviary and need a flying type for my team. In all the other generations I've gone with the starting bird (Pidgey, Taillow, Starly), but the Pidove line...sorry, just can't do it. Unfezant just looks...strange to me. Zekrom has grown on me since then, and the only time I really use legendaries anyway is when I'm battling with my friends casually.
