It's been over a year since the last post was made, or even the last suggestion so i figured i'd add my 2 cents.
pokemon.
Voltorb/electrode should be and easy 3 pic icon, ball that rolls, with a red side/white side, not to hard...
Shinies random chance of one of the pokemon in the maze being shiny every 1000 times the maze is accessed...
Higher level AI pokemon, maybe an area to the sides of the current zones where pokemon already spawn, with the higher level pokemon... so low levels can still train with minimum danger.
Breeding... currently, you would go into the Nursery two pokemon would marry and then create an egg.. great, but automated... what if there were player run Nurseries, Players would get to run the nursery i.e. any two pokemon trainers bring to the Nursery is deposited and become ai, the keepers would have to grow food, make poffins, and take care of the pokemon through feeding and what not... after a while of taking care of the pokemon, an egg is created... (the player who dropped off the egg would have to check back in 2-3 days), if the keepers dont do anything, a regular egg is created, normal egg normal way. If the keepers work on the egg... there's a chance it'll be shiny, 1-5000, . If the keepers are diligent on working on the egg, there's a better chance, 1-1000
Keepers level by takeing care of pokemon, (exp) and making foods (exp). various food makeing items are dropped... of ai pokemon through the worlds, (sold to the nursery).
This would allow players to have something else, to do and various nurseries could open in different towns... having different levels... i.e. you have a level 3 nursery it'll have a higher chance of createing a shiny egg... but if those players are not working on the eggs... then the level 1 nursery would create a better egg than the level 3.
