I think every different pokemon should have its own egg pattern, that way they are identifiable even as an egg.
EV's should be listed in the summary
There should be more than one file per game
or maybe
2 completely different games in the same region..
a normal file
the 2nd file can be a tag team / twin file where the user controls 2 trainers.
i think that would mean 3 pokemon per trainer since no double trainers had more than 3 each anyway and 12 pokemon is kinda hard to train at once.
the 3rd file is like normal but you need wifi on to play it.. u play normal but can interact with real trainers wandering about and chat and talk with them so there are no computers or something like that.
16 badges like from the G/S/C era.. where you explored 2 different regions
the pokemon league in the game and tv series are completely different..
so thhey should have the elite 4 and the pokemon league as a tourney with certain rules and restrictions which change every week through the
DS clock or is downloaded from wifi so everyone has the same tourney at the same time.
more trainers in the game that have pokemon at higher levels like in the 70's, 80's and maybe even 90's.
Wi-fi contests.
