Ruby. Ruby. Ruby. Ruby. Ruby.
THE best Pokémon game ever. Most people get nostalgia fro G/S/C, my brother included. As for myself, Ruby is what I think of when you say 'Pokémon' to me, if not sprites. Seriously, why does everyone hate Hoenn? Having played Fr/Lg/Yellow and Gold (although not for that long, about a week?), I can't see why hardly anyone likes the game. I've played Ruby so many times over that a) it's the only cartridge in which I raised a Pokémon to level 100 on my own (at the age of 8), and b) the internal battery has run dry. XD It's a great game.
And if not Ruby, FR is nice. I just play through it when I'm bored.
Nostalgia-wise, Ruby comes first and Yellow come second. Yellow was the first 'Mon game I'd played before, but I was really young, like 4 or 5, so i don't remember it as much as Ruby.
I'm going to start an Anti-Anti-Hoenn club. D=<
