If my play through could be with my favorite pokemon I am going to go for it every time. Otherwise then entire time I am playing I will be thinking "Yeah, this is cool, but I wish I had gotten Riolu." I don't want to regret my play through. That is a sour experience and I want to experience this game in the best way possible for me. Saying that it is "a bad excuse" to want to play a game with my favorite starter is pompous and insensitive.
I guess I will wait for the full release or keep on grinding for the Jackpot Riolu.
