>>24776994>Gen IOpenworld factor, caves/dungeons actually being multifloor dungeons, and legendaries hiding in their own dungeons tat you have to actively seek out and find
Also have Missingno/Glitch City-like glitches that don't actually harm the game but add fun to it, along with just general oddities that contribute to urban legends and deepest lore theories.
Having the rival always be one step ahead.
Sprites that actually show action and not just static poses.
Move sound effects.
>Gen IIHaving a sister region you can travel to post game with full 8 badges, but make it actually difficult and full of things to do.
Caves that have multiple exits in the vein of dark cave and Union cave, but no shit like Dark Cave's "you can only actually traverse the exits when going down so this cave is pointless".
Having a rival
>Gen IIIDefinitely take the overall speed and fluid transitions between routes and cities without loading screens, also secret bases and contests.
More hidden shit like the Regis, Battle Frontier, region that actually feels connected and makes sense with beautiful environments.
