>>18831883Megas removed, 'mons like Mawile who needed megas get their Mega as permanent evolutions. 'mons like Ampharos who needed buffs but were at their 3rd stage of evolution get stat buffs and in some cases their mega ability or type.
Fairy renamed to
Light. all fairy types keep said type, but some others such as Lucario get it.
Shadow type is now a thing. Rather than having to purify Shadow pokes, there are new species that are shadow by default. They are all shitmons statwise and carry only Shadow moves.
Game allows you to catch 20 non-legendary pokes from each prior generation, and introduces 130 new ones. The regional dex contains 250 Pokemon. There are no legendaries before the national dex and all of them can be obtained in some way.
Weather stones for every terrain, weather, and trick room. Stone to increase grassy terrain can evolve Eevee into Leafeon and the stone to increase hail can evolve Eevee into Glaceon.
Ice now resists Grass, Flying, Ground, Bug, and Normal.
All HMs are passive abilities now that vary on species. For example, Bibarrel now has access to Cut, strength, waterfall, surf, rock smash, etc. at all times without any of them taking up a move slot. However, they can no longer be used in battle. HM moves like surf that don't suck are renamed and added as TMs.
Default characters look like Red and Leaf, character customization allows you to look like any other protagonist. Also allows you to look like the rivals. This includes rivals and protags from spinoffs (Wes, Snap protag, Ash, manga Blue, etc.)
Crossdressing. Seriously Game Freak, even Animal crossing did this.Evil team that isn't edgy or stupid. Maybe legit Pokepeta, but I'm sure there's a better option.
Option for challenge mode, doubles mode (every battle is dubs), triples mode, multi battle mode, etc. this has no impact on story (sans multi battle, in that there is 2 trainers for every major fight).
Music that isn't as shit as X/Y.
