They don't, but avoiding the mention of time travel is a fairly logical choice when it comes to promoting compatibility. Why make things cumbersome? One could argue that there was no incontrovertible proof at the time that the Hoenn and Kanto games were concurrent, but there was no reason to think otherwise, either.Originally Posted by Ranger Jack Walker
The reason we even know when Generation V roughly takes place, is that Game Freak wanted to reference the Generation IV games. They did it in such a way that reminded players of the other DS games (Platinum and HGSS) that are still relatively new, but less advanced than Black and White. How would this work with remakes that would be equal in terms of gameplay? Why are there so few references to Hoenn right now?
