This is a very unique feature I have been impressed with the past few months. Before a game, for example, I'd play against my brother on Christmas Day and the commentators would state "Merry Christmas..."

And it wished a Happy New Year Year and Valentine's Day when we played those days.

Just for fun, I decided to see if it would wish a Happy St. Patrick's Day before the game. Yep, it did.

Does anyone know if it works for Ash Wednesdays or Good Fridays? And are there any other sports games like this?

Yea, it's kind of neat. I think NBA Inside Drive does that as well.

I kind of doubt the Good Friday or Ash Wednesday as those are more closely tied to religion (and yes I realize Christmas, Easter, etc are religious holidays but are also celebrated as secular holidays)
