My favourite generation is the one I have nostalgia for and the first one i played, Gen 3
Ruby and Sapphire i think had really good pokemon designs especially my favourite legendary Groudon, he looked metal as fuck on my copy of Ruby. I enjoyed the soundtrack from the GBA version and matched the anime based from it, Pokemon Advance.
What is your favourite generation and why? What details makes it stand out for you?
specifically the pokemon, or the games ins aid generation.
gen 5 is imo objectively the best generation in terms of game content (virtually every game after black 2/white 2 has less content)
aa for pokemon designs, slight edge to gen 3, with 4 and 7 not particularly far behind.
