Why is Pokemons the ONLY JRPG where Grinding is Fun/Acceptable?

On another note, the only downside to grinding in Pokemon, in my opinion, is PP is limited so you can only use Flamethrower, Zen Headbutt, Earthquake, etc. so many times.

That's why you stay relatively close to a Pokemon Center. Free PP Restoration.

That's how i made the big long pre-Elite 4 grind tolerable, just hang out in the upper level of Victory Road and periodically return to the Pokemon Center

Especially necessary in Ruby/Sapphire.
