DRM on digiital games?

I know the PS4 has DRM on its digital games and u need to be connected to the internet to play them. Is the X1 the same? I'm debating buying some games digital but not if it means when my internets down or im travelling I can't use them.

Thanks!

I can play my downloaded copy of Madden 25 in singleplayer with no internet connection.

Yes, you can play your downloadable games offline. To be honest all you had to do was a quick Google search to find this answer out for yourself.
