-8 Gyms (Why must it always be 8. Orange Islands in the anime had 5 did they not?) The Orange Islands had four "gyms" plus the champion. Eight gyms is a tradition, and it works well with the level curve. Consider how badly the 16-gym system threw a spanner in the works for Johto/Kanto. The level curve there is terrible.
- An elite four. Why would all regions have an elite four? Even an elite 3 or an elite 6 would be a nice change of pace. Or something new all together. Based on Japanese and Buddhist tradition/mythology. The Shitennou, in Buddhism, were the gods of the cardinal directions, and in Japan the term was used to refer to the four most powerful subordinates of an emperor, hence why the Elite Four are directly called Shitennou in Japan. It's a historical thing.
- A professor. I don't even need to explain this one. Actually, I would appreciate if you did. Why don't we need a professor? It makes sense that a skilled researcher would be the one to give you a Pokedex and a rare Pokemon to start out with.
- A fire, grass and water Pokémon. It's just not necessary. I did however like how they made some final evolutions double typed to make them different (Charizard, Swampert, etc) Necessary? Perhaps not, but it is tradition, and the Fire/Water/Grass triangle is one of those perfect ones that works to teach beginners about type differences. Not everyone has been playing since Red/Blue, after all.
- Team -insert name-. Just...meh. All right then, what would you suggest for the villains to be?
- A "good" rival. They've done it in every game since third gen (May, Lyra, Barry). (Although Lyra wasn't a rival, she follows a similar trend, and there will likely be the same in BnW. Point is they will probably repeat it just because they did it once...) Gary was more fun to fight because he was actually a rival. You actually wanted to kick his ass because he was so cocky. The "good" rivals just felt like little sparring matches. Well, we don't know enough about the rival(s) of Black/White yet to say what they're like. And a rival doesn't need to be cocky to be a rival. The very definition of a rival is a worthy opponent that provides an equal challenge. Wally was more of the rival for the Hoenn games, anyway, and while they could have expanded more upon his character I think him overcoming illness to make it all the way to Victory Road was impressive.
