Which brain training game for DS?

[littletreasure]

I'm thinking of buying a DS Lite very soon and would like one of the brain training type games. There seems to be a few out now and I wondered which one people preferred.

Thanks

Brain Training hands down, I'll tell you how good MBT is once it arrives.

Kawashima - the original and the best.

Thanks for the replies. I'll have a look at Brain Training.

Big Brain Academy is also fun for a little while, but it's not as in-depth IMO as Kawashima's, nor does it seem to have the addictive replay value as the latter when trying to beat your scores/times - as a poster above said the sequel is out in a couple of weeks...

If it's anything like the Japanese version the second one will have a lot more games, so I'd go for that.
