Your favorite pokemon game of all time?

Pearl, definitely. I've played through it so many times, but I'm still not bored with it. Sometimes I wish I had gotten Diamond because of Stunky/Skuntank, but I like the Pearl exclusives just as much.

My favorite? Ruby. But only because it was my first and I played it for so many years I have lost count.

Realistically though, I consider Emerald and Platinum to be the best games, with Leaf Green/Fire Red close (SS/HG are great but incredibly flawed and B/W was garbage in every way bar the pacing. B/W2 I have not played and I do not plan to.)

EDIT: Oh, do spin offs count?
Pokemon Pinball Ruby/Sapphire it is then. I love pinball and R/S did it so right and uniquely I'll never be tired of it. Pokemon Colosseum and XD are also just as special as Ruby is for me.
I also loved Pokemon Channel back when it was first released. Screw what everyone may think of it, it was magical at its time. Mystery Dungeon Red/Blue come close too. I'd like to give special mention to Pokemon Ranger as well, because it made a great showcase to the DS and was really fun at its time.


....My answer is Pokemon Pinball R/S and Pokemon Ruby. Don't mind me.

Platinum.
I started with Diamond (let that sink in...), and I thought that was an amazing game..so when I heard Platinum get announced (I even have a poster for it in my room), I just said that I was surely going to buy it. I bought it, and played the hell out of it. What I loved were all the small, but really good changes from D/P's gameplay. Adding the Battle Frontier, something I loved in Emerald, the Distortion World and Giratina's new form, which looks sick. The small storyline changes, adding Looker and Charon, and Galactic's new plan...it was all good.

Either Emerald or Mystery Dungeon: Blue Rescue Team. They both entertained me for hours on end as a kid, and both brought to light my love of Rayquaza.
