Elements like Jessie and James NOT having Meowth follow them and for them NOT to literally attack you at every turn. And yea, no Brock/Misty following you/helping you in battles. And Pikachu does NOT shock you arrogantly before you grow attached to it, it simply remains neutral in-game.
But the fact that there even IS a Jessie/James duo and even having Giovanni's Rhydon/Kangaskhan replaced with a Persian was a neat twist. But Sabrina doesn't have a lone Abra when you fight her in-game; she has Kadabra and Alakazam as well, and evolving DURING a match, really? (Also applying to Koga's Vanonat in the anime as well, seriously, what??) Oh, and kids, if you watch the show first, you might be told (albeit in an implied fashion) that Haunter (or Gengar, but we're focusing on direct links to the show, meaning the ghost Ash actually caught) can somehow defeat Psychic types and not suffer that much consequence. .....I'm gonna get ranty here, because the show's writers apparently forgot about the fact that all Gen1 ghosts are ALSO COUPLE WITH THE POISON TYPE!!! So why even, in-game, go through the effort of raising a lv30-50 Gengar to fight Sabrina, when YOU WILL MOST LIKELY LOSE! That's right, kids, your favourite anime's writers are either not interested in the game, or out-right lied!!
Moving on to my favourite part; the fact that Yellow is the only game.... That. Legitimately. Gives. You. ALL. THREE. STARTERS! A crazy concept at the time. (Sure, X/Y gives you a Kanto pokemon, and many such examples which would warrant its own post.) But, seriously, this means that you get to roam throughout Kanto with a Venusaur, a Charizard AND a Blastoise. Childhood me, high five!
We may have individual points to criticize on both the anime and game, and no opinion is really wrong. (So long it's not a trollish 'Gen 1 is always superior/inferior!!') I've prolly forgot to outline a few crucial details, but I got a few of em down! :nod: Hope you learn a bit from my opinions. :wink-right-eye: And thx for being awesome!
