Brain Training/Brain Age

Hi. I know they're not games as such but can anyone help with this query.

I purchased Brain Training with the DS console and after a few weeks I decided I wanted another but different "game", so I purchased Brain Game.

The packaging is different and Brain Game states it is for the US/Canada market and when I started playing it, I found it was exactly the same as Brain Training.

I now suspect that they are in fact exactly the same apart from the name and one is for the UK market and the other for the US. Am I right?

Pis.... me off, as I can find no warnings anywhere that they are exactly the same apart from the name.

There are several games that have different names in the different versions. Digimon World and Digimon Story are the same game, as an example.

I don't know if what happened to you is the same thing...

Thanks. I've now had it officially confirmed by Nintendo that they are the same but with different names for different markets.
