Crystal!

Ruby and Sapphire, 100% because of nostalgia as I haven’t played either in 20+ years - those were the last games my grandpa gifted me so they hold tremendous sentimental value.
Gold and Silver would be close seconds, since my sister and I played those games when growing up and I have great memories from back then.

Emerald holds a special place in my heart. Omega Ruby got me back into Pokemon and to this day is my favorite. I’m currently playing through every generation, but no other region hits harder that Hoenn

Crystal is very special to me. I always felt like I was “wrong” as a child for not liking “girl things.” It was the first game I ever played that offered a female protagonist. That was something that told me that I was okay the way I am. I know it’s kind of silly, but it really helped me become comfortable with myself.

For Nostalgia? Red/Blue and Gold/Silver.

HG/SS and B/W are up there too for different reasons.

And funnily enough, I actually enjoyed S/V quite a bit. Aside from the lull between gens 6 through 8ish, there’s a lot to like throughout the series imo. A lot to dislike too, but still a lot to like.

Crystal (mostly nostalgia), Emerald, and Conquest

I played Gen 1 as a kid and didn’t play Pokemon again til Black and White. It was an amazing leap to see the first and last pixel animated mainline Pokemon games, and both had their own unique set of 150 Pokemon. It’s like a showcase of how much the series had grown.

Incidentally, it was the last mainline Pokemon game I actually enjoyed.

I have a soft spot for Crystal, in terms of the official series.

If we include rom hacks, Crystal Clear is great, and I’m really enjoying Pokemon Emerald Rogue these days.

Um… one of the later ones for the 3DS. But I think these new ones coming out soon will be super awesome. I don’t play many Pokemon games though.

I’ve played Blue, emerald, black? For 3ds? And that’s it.

For me i would say silver for the nostalgia factor, Also silver (and gold) were compatible with the original black/white gb so Even more nostagic than Crystal

I put the most hours into soul silver, but god, I fucking loved Prism

(Soul)Silver for nostalgia, Emerald for favourite to replay

Fire red will always be my number one as it was my first game.

Otherwise it’s a hard choice between Sapphire and Heartgold. Both had great regions and lots to do.

My most played would be Diamond and it was good, but sinnoh was never my favorite region.
