2 Criket Games on Xbox? Really...

I know Cricket is very popular in the UK, Australia and New Zeland but I would have never expected two games for the Xbox. Im curious how many units they sold, at least that way I could verify their rarity. The seller claims they are rare.
As far as I know these were not sold in the U.S.

* EA Sports Cricket 2005
* Ricky Ponting Internation Cricket 2005
