I really loved Ruby/Sapphire, although looking back I loved HeartGold/SoulSilver so much because I never got to play the originals...


Still haven't got to the first gym on Pokemon X yet.

Platinum

I miss the simple times of the earlier games...

Crystal remains unbothered as the best!

emerald, Y, colloseum, crystal & platinum are my fav 5 in that order

HG/SS is my favorite game for sure. I mean this is like the only really difficult one to beat fully.
The Emerald and R/S cause they were my first and I think had the most fun and diverse region.
Then Gen 6>Gen 2>Gen 1> Gen 5 With BW2 better than BW > Gen 4 with D/P/P

Emerald <3 the first one I completed.

Platinum and HG/SS.

Gen 4>>>>

silver and gold.

Crystal aka the golden era of my childhood.

Crystal was pretty good besides the old school graphics, which were fixed when the remakes came around so I'll have to say HG/SS.
