>>36282808in terms of QoL features and balance, the newest games are the best ones. you might want to go backwards, first to gen 6, then to 5, then to 4 and then to 3 (but you will probably be sick of pokemon before you reach that far). I'd recommend omega ruby or alpha sapphire first. they get a lot of heat on here for not having the battle frontier, but as someone new to the series, that probably won't mean shit to you.
gen 1/2 are extremely slow and lacking in QoL features, forget about them.
