I think Jeff said in the QL of this game that running through tall grass has a higher chance to attract wild pokemon battles. I have been playing pokemon games forever and never realized that this happened. Is it really true, or was Jeff totally wrong?

Yes it is true. I actually only realized it when playing Pearl a few years ago. Don't know if it is a new feature, but I aint running in no tall grass anymore.

Excuse me if i'm being an idiot but I don't remember the option to toggle run/walking in Pokemon : Crystal?

Is there actually?
Or as you are running are you hitting the battle quicker than you would have if you were walking?
 
Does that make sense?
 
I stopped playing Pokemon at Red, just gimme a Dragonite and Charizard and I'm a happy man.

Yeah it's true. Also, cycling gives you even more of a chance to encounter wild pokemon than running.

There is a guy in town when you get the shoes. He tells you that running makes more noise and attracts more wild pokemon.

" @JJWeatherman: running did indeed begin with Generation 3 as a way to make the movement a little less stilted, some may also notice a welcome lack of Zubats in most of the caves in HG/SS, this was a specific design choice, as everybody hates Zubat, specifically late-game. "

really? I always knew that. ever since silver. 

I never realised this, perhaps because after Gold I never played until Pearl (or was it Diamond) and I didnt play a lot of it. Although ive replayed Blue a bunch of times on an emulator (because the gameboy dosent have a backlit screen so its hard to play) and use a speed toggle to run places since im lazy.

As I walk into the fucking grass in every Pokemon game to fight and grind my kids and I make circles there on purpose, I never noticed that.

Yeah ive known that for a while.

This is true.  Also riding your bike makes Pokemon come even faster then running.

Definitely true.  This is why I always took out my bike and rode around like mad when I was doing some intense EV training on my Ghost team: it made the whole process faster.

The obvious solution is really just to never move anywhere, ever.

i think it increases your chance to encounter a wild pokemon per unit time but not per step. Your chance to encounter a pokemon in any given step is the same, but you step faster.
