Hey,
okay I'll just list my ideas
-Housing = every city will has a house . those houses will cost a money and player who bought them will be able to decorate the home,invite friends,duelling and trading pokemons. Maybe some background music and house theme can be added for future of that idea.
-technological mounts = motorcycles, skateboards, rollers and scooter(motor one). those will add some variety to mounts.
-improving jet skii animation and older mounts animations = what title says. jet skii looks like a coin eating circus toy.
-Adding more events in stories of regions = okay title can be confusing but think about it. events will make you earn pokedollars , pokeballs, maybe even new npc trade opportunities. like side quests and social things to accomplish for a reward.
- adding a pokebar or pokecafe = for people to chat and have fun and relaxing. because chat is not a place to troll and making humour.
-Reputation syste = defeating team rocket grunts or bad guys will reward reputation and gym leaders will reward too. after brief amount you can buy cosmetic items from mayors.
-barbershop = what title says. a place for hair dye and change.
-customizable trainer card = writing your own information and letting other trainers to see your card. its kind of a nice social thing.
-pokemon fight encounters animation = a short and old school animation would make it nicer.
-changing bag screen to fire red theme = what title says
those are the ideas that I imagined . Maybe more npc's can added for better world population but yea . thats all folks!
