A simple ranking of all the Pokémon games I've played to date based on my personal enjoyment as well as a loose evaluation of various criteria such as gameplay, writing, graphics, and sound.
- revolutionary gameplay direction for the series - comfy setting filled with nice characters
Pokémon SoulSilver Version
- thoroughly competent remake with a grand scope of two well-realized regions
Pokémon Sword
- controversial franchise direction with limited features - appealing modernization in some areas
Pokémon White Version
- best story in the main series - poor selection of new Pokémon without the old ones being available
Pokémon Black Version 2
- significant improvement over the previous generation in everything but story - large and well-put-together Pokédex
Pokémon Violet
- progressive entry with numerous much-needed changes - enjoyable open world exploration - horrible performance given the mediocre visuals
Pokémon Sapphire Version
- my first Pokémon game that also lacks any major flaws - great setting with an unusual focus on aquatic environments
Pokémon Brilliant Diamond
- fine remake that has a lot of positive quality-of-life changes but still can't compete with Pokémon Platinum in terms of content - divisive graphics overhaul with a mix of chibi and anime art in and outside combat
Pokémon Ultra Sun
- good use of 3D environments - surprisingly competent story - irregular setting with a less formulaic progression structure - more mechanics to make the game trivial - painfully slow and guided beginning
Pokémon Colosseum
- uniquely dark story - limited scope for the price of being 3D
Pokémon XD: Gale of Darkness
- gameplay-wise improved but also less interesting sequel to Colosseum
New Pokémon Snap
- competently made but incredibly basic game that demands a lot of grinding with unengaging mechanics
