[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Dies Irae]

We'll be playing in the region of Creshire.

Professor Mallorn rules a "modest" science business empire from the starting town of Trillium in the north. He rides his Rapidash down Breakneck Ridge to the twin capital cities of Cress and Stair City, bearing trade goods and Pokemon, for sale or for study.

He's agreed to provide any of you who need one with a Pokemon from any region (except Alola, I am thinking, but some exceptions could be made).
He can sell you a Pokedex for a mere $1300, an incredible bargain, starting week only.

So, I've actually got a question for Iron regarding the campaign direction: in terms of plot development and direction, how relevant will the 'Dex be relative to the scope of game-play/plot? 

It sort of makes sense for a party to own at least one 'Dex, but out of the starting funds, dropping 1.3k on Pokedex pretty much blows starting cash immediately has a knock on effect of limiting access to Potions and Pokeballs for any character who makes the purchase.
