This is an idea I've had since I was little, since the first pokemon games came out. It's pretty basic, but probably not what this game is looking for in terms of gameplay. Still, it could branch out into other ideas, and possibly be incorporated.

We all know that in the daycare, compatible pokemon produce eggs. For me, waiting for the egg to hatch is very thrilling; I think it's because you don't know what moves they'll have, or even if it'll be a shiny. What if, on random occurance, like wild pokemon encounters, you find a Pokenest, and there is a mystery egg inside. Now, this would have to be on a very random occurance sequence, and the egg, like any freshly caught pokemon, would be sent to the PC. A maximum of 5 eggs could be in the PC at any given time, to keep from egg harvesting. The chance for a rare pokemon is, just that, rare, but the fact that it could be any pokemon would be a great way to keep people walking through the grass, training their pokemon; a suspense tactic.

This idea is rough, I know. But I think it would be a great way to keep players intrigued, and also a new and exciting addition to already great pokemon game.

Critiques are welcome. I'm not afraid of bad ones, so please, post anything you like.
