>>33693693-Chrono Trigger-esque Pokemon encounters that are seamless.
-Semi-Visible Pokemon encounters to encourage exploration. Almost no need to buy repels unless you want to slow Pokemon encounters down
-Real-time day night cycles are toggle-able, can switch between simplified, inverse and to scale
-A lot of design notes lifted from Zelda games. Characters and NPCs emote and make vocal sounds if necessary but not fully on voice acting.
-Some boss battles, be it trainer or berserk Pokemon. To differentiate from a capture, some Boss Pokemon have multiple HP bars
-Some kind of compromise between TM and Pokeride. At least the choice not to wear the dorky suit.
-Can make trainer videos like X/Y
-PokeStar Studios is back
-PWT or at least something similar.
-Diving. Lots of diving. Take some notes from Gen 5 and ORAS.
-Type chart now has scaleable weaknesses. Parameters are nerfed for Super Effective damage (now 1.2x and 1.5x damage, highest stack is 3x and Filter is now buffed as a result. Steel and Rock might share weakness to Fighting but Steel now resists slightly better than Rock taking 1.2x damage from it compared to Rock's 1.5x, etc.,) The idea is to make certain Pokemon less jobbery.
-Character customization ranges from sensible to downright silly. You can even dress like your favorite NPCs.
-Mega Stones have Z-Power. However, using the Mega Stone's Z-move will cost you the Mega Evolution for the battle
-Horde Encounters return
-6-on-6 battles.
-Battle Royals return but with familiar trainers, including --player characters?
-Regional forms continue or something similar
-85+ new "standard" Pokemon, not counting region forms, Starter Megas for the rest of generations. There are also
28 new Ultra Beasts
