Your response can be as long as you like, but must actually answer the question. For example, "I'm planning on using Quaxly in my first Scarlet playthrough because I haven't used a Water-type starter since Gen IV!" would be a good response, but "I'm going to use the green one, just because." would not be. Final judgement on if a sufficient answer has been given will rest with the Bulbagarden staff.
The deadline for all entries is Friday September 16th, at 11:59pm (PDT). Once this deadline has passed, we will randomly select our nine winners from respondents. Winners will be contacted in the first instance via Bulbagarden Forums DM, and then via any other contact details connected to their Bulbagarden Forums account in the event that we don't receive a response.
Due to Amazon pre-order limitations, we can only award up to three copies per geographic region; Amazon US, UK etc. Winners in Canada and some other countries may also be required to answer a basic skill-testing question to receive their prize, in compliance with local laws. As a result of these factors, we will also need to know the country in which you are based, so make sure you've added this information to your account details to confirm your eligibility.

Good luck, Trainers!
