Characters - In terms of main characters I would like to see them basic like Red. I was never really a fan of Lucas or Brendan.
Gym Leaders - I want them to be interactive with the story line like Lenora and Burgh were in the situation at Nacrene City and then again with Iris at Castelia City. And Clay is present during the Cold Storage incident and helps you break the net at Chargestone Cave. Then there was Brycen at Dragon Spiral. Basically I want leaders that actually do something outside of saying "Hey here's your badge good luck kid". And of course I want a chance for rematches.
Champions - I want a Champion that also goes around the region, pretty much like all the others did in past generations and help you out from time to time or fight with you like Lance and Steven did. Hopefully the Champ is no push over either... Maybe give him two pseudo legendary for a challenge.
Criminal Syndicates - Give them high level pokemon, I want more of a challenge. And don't give me the same crappy pokemon to face over and over again. Or at least give me several commanders, cipher, admin whatever you want to call them. 3-4 doesn't really seem like that much to me. And give them more of a back story, cause we got some stuff from N and Ghetsis but when I completed the game I felt like I was wanting more.
Pokemon - Don't go overboard with the inanimate objects. I think people felt that there was generally too much this generation for whatever reason. I personally am fine with things like Ice Cream and Lamps but others are not apparently.
Story - As far as this goes, give me something we have not seen before I don't want it to draw too much of past generations. Keep it new please.
Graphics - Take what you got from BW and improve it. Heavens knows we could get some better back sprites. And use the 3D from the future hand held they will be on and utilize all the potential of it.
Rivals - Can I get somebody like Blue/Gary Oak please? Silver imo seems like he was more concerned with Team Rocket and all their crap then dealing with you. I got the feeling he was looking past me and more for a fight with Team Rocket(so you had issues with your father, well it's fathers day so get over it!). Brendan/May worse rivals ever, you don't even face a full team if I remember correctly and the last match was at Lilycove. Although Wally was a better rival but still not that great I mean we got to battle in Mauville and Victory road whip de do! Barry was too much of a spaz for me, yeah he was your friend more then a rival per say. He was better then Silver and May/Brendan. Bianca and Cheren ehhh. Bianca seems like a pushover, she never really seemed like much of a rival hell she was more concerned with Musicals and being a "bodyguard" then being on equal terms with you. She pretty much admitted that she wasn't too great. Cheren seems like a know it all annoying as hell rival that thinks he knows everything thing, but in fact has a hell of a lot to learn as seen by his conversations with Alder. Cheren is helpful like Barry but no thanks I don't want a rival like him. Too me give me a Rival like Gary who shows up all the time, you know every time you see him he will get better, and he is actually some what challenging(considering he is the Champ at the end), and I love he actually acts like a Rival.
Features - I would like to see the return of Follow Me(optional where you can turn it on and off). Give me something too do rematches with like Phones, Trainers Eye, Vs. Seeker(my favorite).
Post Game - I need stuff to do outside find a couple Sages, then level up for a battle with Alder. I hope in future games that have something worth while to do.
