Kanto and Johto.
The pokemon game that has two regions is gold silver and crystal and the remakes of gold and silver heart gold, soul silver although many of the games have areas you have to take a boat to which is close to two regions but not officially a region
If you mean Pokemon Regions then the answer is no! There are only 4 games with 2 regions and that's Pokemon: Gold, Silver, Heart Gold and Soul Silver!
You can't go to different regions in platinum. The only game that lets you do that is Heart gold/Soul Silver... PS For heart gold and soul silver, the regions in it are johto and kanto even though Hoenn region champion Steven is in it. Hope this helped :D You can't in Black/White either =/
no only johto and kanto but you can get the 3 hoenn starters
silver, gold, soul silver, and heart gold
Heart Gold and Soul Silver
No you cannot go to other regions in Pokemon Pearl or Diamond version but in Pokemon Heart Gold and Soul Silver you can go to the Jotoh region.
No. The only 2 regions you can go to in Heart Gold and Soul Silver are the Johto and Kanto regions. However, you do meet Steven twice and obtain a Hoenn starter Pokemon. Also, you can find Latios/Latias as roaming Pokemon after meeting Steven for the first time.(Soul Silver=Latios, Heart Gold=Latias.)
