The developers then announced through a series of tweets that the game would ship with a 'stripped-down' version of story-progression (a gameplay mechanic controlling neighborhood autonomy), and that basements, grocery stores, and school and work locations would not be featured in the game. Earlier in the development process, a fan-site interview with a producer had revealed Create-a-Style (CAS), a customization feature introduced in the previous Sims game, would not be added to The Sims 4 in lieu of other features. On February 2, they announced via the official The Sims Twitter feed that the Mac version of The Sims 4 would be released on February 17, 2015.
