It's the start of a new month, which means a new batch of games have been added to Xbox Game Pass. Subscribers to Microsoft's game service now have access to seven more titles on Xbox One, with an additional game arriving on April 11.

Beginning April 1, Game Pass subscribers can play the Xbox One edition of the acclaimed city-building sim, Cities: Skylines. That includes both the base game and its After Dark expansion. Players can also create their own mods and share them online thanks to a free update that arrived for the game last month.
