5th Gen The feeling of the two games

Is it me or does white2 and black2 feel different from each other. Got white 2 for competitive play and it just feels completely different like its a seperate game from each other even though they are the same with a very variations. Is it just me or Is there something to this?

They both have much more distinctive differences than any other Pokemon title (here's a list of all the version differences) but I wouldn't really say that they were completley different games.

If you are talking about B2/W2 and B/W then they are much more different games than each of them due to them being direct sequels.
