In Pokémon Red/Blue/Yellow, the key feature was the basic Pokémon battling and catching system. For Gold/Silver/Crystal, it was the day - night cycle and new Pokémon. Ruby/Sapphire/Emerald had the unique Pokémon abilities. FireRed/LeafGreen had updated graphics of the originals. Diamond/Pearl/Platinum introduced the Sinnoh Pokédex. HeartGold/SoulSilver had the Pokéwalker. Black/White had a story focused on truth and ideals. Black 2/White 2 continued that story with new areas. X/Y had Mega Evolutions. Omega Ruby/Alpha Sapphire had the DexNav. Sun/Moon had Z - Moves. Ultra Sun/Ultra Moon had more story content. Sword/Shield had the Dynamax and Gigantamax. Brilliant Diamond/Shining Pearl had updated graphics for Sinnoh. Legends: Arceus had a more open - world exploration and different catching mechanics. Scarlet/Violet had the Terastal phenomenon.

Well, starting with Metroid which introduced us to the world and the main character Samus. Then came Metroid II: Return of Samus which continued the story of Samus' battles against the Metroids. Super Metroid is a classic that further developed the story and gameplay. Metroid Fusion added new elements to the story. Metroid: Zero Mission was also important in the story's progression. The Metroid Prime series, including Prime, Prime 2: Echoes, and Prime 3: Corruption, told the story from a different perspective but still within the overall Metroid universe. Metroid: Other M and Metroid Dread also added their own twists and developments to the ongoing story.
One of the key games in the story order is 'Castlevania: Symphony of the Night'. It's a classic that many fans consider a must - play. Another is 'Castlevania: Aria of Sorrow' as it introduced new elements to the story. And 'Castlevania: Dawn of Sorrow' which continued the story from 'Aria of Sorrow'.
In my opinion, 'Pokemon Black and White' has an excellent story. It delved deeper into themes like morality and the relationship between humans and Pokemon. The story challenges the player's view of the Pokemon world in a new way compared to previous games.
I think 'Pokemon X and Y' has a really good story. It has a more modern - day feel compared to some of the earlier games. The story of the Kalos region is filled with mystery, especially regarding the secrets of the Mega Evolutions. The characters like Lysandre add a lot of drama to the story with his extreme views on creating a 'better' world.
In my opinion, 'Pokemon Black and White' has an excellent story. It delves deep into themes like morality and the relationship between humans and Pokemon. The story challenges the player's perception of the Pokemon world and features a great antagonist in Team Plasma, whose ideology about separating Pokemon from trainers is thought - provoking.
I would also put 'Pokemon Sun and Moon' high up. It had a very different and refreshing story. It focused on the Alola region's unique culture and the trials instead of the traditional gym battles. The story was more about the player's journey of discovery and friendship in this new region.
Well, for me, 'Pokemon Platinum' is high on the list. It expands on the story of 'Pokemon Diamond and Pearl' really well. It has a more complex plot involving Team Galactic's plans and how they impact the Sinnoh region. 'Pokemon Sun and Moon' is also great. The story is more character - driven, focusing on the relationships between the player, their friends, and the Alola region. It has a unique setting and a story that's different from the usual Pokemon formula. And 'Pokemon Ruby and Sapphire' remakes, 'Omega Ruby and Alpha Sapphire', have a good story that refreshes the original plot with updated graphics and some new plot twists.
