For all that we know about Pokémon Scarlet and Violet, there’s a whole lot we don’t.
Yes, you can tackle gyms in any order you please, but it’s unclear how exactly that’s applied, whether there’s some sort of level-scaling (where enemies level up with you) or level-suggesting (which offers suggested levels for various subregions).
Based on geographical and architectural references, it’s clear Scarlet and Violet’s setting is based on the Iberian Peninsula (the westernmost region of continental Europe, comprising Spain, Portugal, Andorra, Gibraltar, and parts of France). But the name of the region remains under wraps.
The two legendaries, Koraidon and Miraidon, are available in Scarlet and Violet respectively. Some previous versions have allowed you to eventually capture both legendary Pokémon. You’d catch the version-specific one (the one on the box art) at level 40. Way later on, you could catch the other legendary at level 70, at which point it’s naturally weaker than a Pokémon you’ve leveled up to that point. It’s unclear yet if Scarlet and Violet will do the same.
