I want to see updates to the first 2 generations and their stats. There are so many that are very underpowered by today's standards like Sandslash, Parasect, Venomoth, etc.
Wouldn't be surprised we see a lot of evolutions to older pokemon as tends to be the trend (1st generation all new of course, 2nd gen lots of new but also a lot of evolutions to 1st gen, 3rd gen almost all brand new, 4th gen lots of evolutions to old ones, 5th gens all brand new).
Difficulty Mode - One that you choose at the start, not all this beat game then send code to another bullcrap.
Traning Centers - Somewhere where you can let a pokemon stay and they would slowly train his EV points in a certain stats, have a seporate lesson for each stat. have this be seporate from DayCares. Have this work from a formula of steps you take just like the DayCare.
Flash - Need I say more, get rid of it and give our character a flashlight for once.
