I actually love breeding Pokemon, simply for the sake of making babies with interesting egg moves or cool genetic histoy and stuff. I've always hoped Nintendo would expand on it in the future - introduce pedigrees and interesting changes that'll occur if you breed certain Pokemon or types.
I think it's a cool idea but you have to be realistic. I personally would like them to stop adding new Pokemon for a while so they can REALLY flesh out the game's mechanics. Otherwise, we're put on a steeply increasing number of required sprites.
See, the thing is, if you do it in a certain way, it wouldn't HAVE to be difficult. For example, introduce type changes - if you breed, say, a male Fighting Type with a female Pikachu, the baby Pikachu might have a Fighting egg move, right? So, breed THAT baby with a Fighting Type again. Do this three or four times and - poof! - suddenly you have a Pikachu that's Electric/Fighting! Make it so that the color gets a slight change and you've suddenly added in a whole new feature.
And the spritework wouldn't be too hard, either. Just apply a "filter layer" to every sprite type - like, all of Pikachu's yellow fur - and make it partially transparent. So, when it gets the Fighting Type, color in that layer brownish. Now Pikachu has a brownish tint. Or, with a Water Type, apply a blue layer - now it's a bluish tint. Keep this up and eventually you'll have a Pikachu that's no longer Electric and PURELY another type. The more you breed it with Type X, the darker it's tint will be... one tumble with a Water Type, and it's just barely visible. Keep it up for generations, and now he's nearly pure-blue.
They'd never, EVER do that... but man, wouldn't that be awesome?
I dunno, I don't like the idea of a Pikachu that isn't even partially electric. That seems wrong to me.
Also, when I was talking about sprites I was mainly refurring to the introduction of new Pokemon. For example, in future Pokemon games, they'll introduce new Pokemon and (possibly) increase the number of sprites used by each pokemon (for animations and what-not) as well as make new sprites for all the previous gen pokemon that can be imported into the game. That's a lot of sprites to keep up with, and its going to take up more and more space in the game and more and more time from the sprite artists.
But then again, I don't really know what I'm talking about.
Mmm, but the size of the handhelds also continues to increase. I'm not even certain there IS a ceiling in that respect, honestly - eventually your Nintendo-built handheld will have graphics just as good, if not better, than the hottest PS3 game.
If they keep things mostly 2D, there really shouldn't be a problem.
johnny: Agreed fully. It needs more to do though, more than just being able to finish the Pokedex, beat every Trainer, etc. Like the Battle Frontier, that was good fun. But we need moar.
A 3D Pokemon RPG would be great, and your 'hybrid' theory sounds interesting, as long as, say, Pikachu remains an Electric type...but what about Pokemon that are already hybrids to begin with?
Well, Pokemon have "major" and "minor" types. Salamence is Dragon/Flying - he would lose the Flying Type and gain Type X, which sounds odd, but he could still LEARN Fly and such. It would be the same in all cases EXCEPT for Normal - Normal Types would be replaced with the other type in a "hybrid" Pokemon's case, mostly because of Flying Types.
Looking back, Pokemon losing their types DOES sound kinda crappy... but gaining another, that's the ticket. Seems odd for a "main" Pokemon title, though... something like Pokemon Breeder would be SWEET, though.
Oh, maybe it would be a side game for the main console, or something - you can transfer Pokemon there, breed them, read their pedigrees, plan everything out... and once you're done, you can send the babies back to the main game with the perfect nature and stats and everything you'd want.
It works for the competative, you don't need to put up with finnicky eggs anymore. It works for the creative, who can make their own Pokemon, almost ENTIRELY unique.
And it could double as "Pokemon Box" dealie, too, so you can store all them Pokebabies.
