Well seeing as i've got this much interest in the space of 2 hours, i'll have more time to get the OOC up. I'd expect Thursday evening at the very latest. Might be worth to start considering what you want your main party to be. 

Dibs will work in this way:

-Each person picks 6 pokemon to have dibs on
-Each will have a number 1 to 6 (1 representing most wanted and 6 least)
-If nobody wants one on your list then great
-If two people want the same then the one with lowest number will get
-If both are drawn it will come to whoever has had to make the most adjustments and if still drawn, first come first served

How you get your Pokemon:

-Once your list of six has been confirmed, you must pick one to be your starter (it doesn't need to a starter in line with the games, but must have 2 evolutions as all game starters have had previously)
-The rest can be caught traditionally, swapped with random NPC's or any other unique way that you can think of (other than theft).

Other Notes:

-You are not limited to the six on your dibs list, it is simply that they are guarenteed to be yours.
-No duplicates amongst the group of players, so no two players could have a Pidgey. Only exception being Eevee although it must be made clear which evolution will be taken. Given the number of Pokemon i'd just rather not see the same spammed over and over.
