I just can't understand how Generation I is contemporary with Generation III or how Gens II and IV are contemporary with each other. All I'm seeing is "Generation X is comtemporary with Generation Z" or that "Gen X seems to be contemporary with Gen Z", but where has that been proved?... I'm not saying that's not true, I'm just saying I find that puzzling and interesting. [[User:Sipulichu|Sipulichu]] 00:34, 12 August 2008 (UTC)
:Hoenn and Kanto take place at the same time is a weak bet, but it's mostly because you don't need a time machine to trade between the games. Therefore, they must trade at the same time. Gen 2 and 4 are contemporary because of: A. the Red Gyarados report at the start of DP (which must happen before Gold/Crystal captures/defeats the Gyarados), B. References to Elm's RECENT report on eggs, and there are more, but those are two of the big ones. Persumably, it takes 3 years or so for Pokémon to reach Sinnoh (Assuming by land, on foot) from Hoenn or Kanto.
