Yes, they are different, but not VERY different.
This has been answered many times before. Anyway... Pokemon are different (e.g. main legendary), places are different (e.g. Black City / White Forest), and there are different battles.
Pokemon White is the latest installment in the Pokemon franchise. It was released simultaneously with Pokemon Black, a game quite similar to White, but with a few different Pokemon. White and Black were released exclusively for the Nintendo DS.
You can't.
The difference is is one game you get different Pokemon like in white you get thunderous in black you get tornadus or in white you get zekrom and in black you get terrakkan.It is just different Pokemon you can or can't catch.
You cant because they are different generations
The experience is different
You cannot go to different regions in Pokémon White.
