The PokePurchase Easy Networked Internet System can solve all your Pokemon Starter needs!
1Tired of putting an unsightly number of Pokeballs and Tables into the Professor's Lab to contain every possible Pokemon you want the player to choose from? Simply use the PokePurchase Easy Networked Internet System(TM) to let your player immersively select his starter from a long, long list! Any Pokemon you want from any region can be on the table, without having to worry about immersion or aesthetics!
Additional fees and monetary checks optional. Perfect for letting the player purchase pretty much any Pokemon for the right price, even Legendaries and Event Pokemon. You can even order some... unusual things with this machine. Can also come in the form of a mail-order catalogue and next to a phone on the wall, for that gloriously retro feel!
In fact, you could even program this as an optional feature in every Pokemon Center's PC, or fill the world with different PokePurchase Easy Networked Internet System computer terminals and mail-order catalogues with wildly different options to select, if you do not want to save time by linking all PokePurchase Easy Networked Internet System computer terminals to the same online storefront.
The PokePurchase Easy Networked Internet System(TM). Or "The PP System" for short!
Heh heh, "short PP". I'm pretty good at game design, huh?
It kind of bugs me that Essentials doesn't show a picture of your starter or play a sound effect by default when selecting a starter.
