So my ideia is to add quests and Advacements to the game quests wold be some simple tasks like:
Kill 1,10,50,100,200,500, Pokemons- Receive ...
Level up your Pokemon 10,20,50 times- Receive...
Win against trainers 10,20 - Receive...
And the Advancements would be like:
Find 1,5,10 shinys- Receive
Capture all the legendarys on a region or on the pokedex-Receive
Complete a Region-Receive
Basically the quests would be a small source of money or some items to make people engage more on the game and focusing on other things than finishing the game.
The Advancments would be a more difficult quest and with higher loot received and in some way we could make some badges to appear on the person profile to make people more interessting on doing the advancements.
Sorry for my bad English.
And btw i wold love to help the developers doing this if they want to implement it, maybe just helping on giving ideias to quests.
