Hi,

I was going to buy both games today. Did they take them off the store? I can't find them, only see a preview of the page via Google.

Visible and currently on sale for me, bought them in NZ a few days ago.

These links are working for me.

If they aren't working for you, maybe the game is unavailable in your country due to content.
