In the latest article by IGN, The Sims 4 team confirms that Achievements will be a part of the game. SimGuruGraham confirmed that the “50 Mile High Club” achievement is unlocked when Sims “Woohoo in a Rocket Ship”.
The night ends with Andre the victor, as he finally works up the courage to pick up a girl, then takes her out for some “woohooing” in a rocket ship parked out back (Achievement unlocked: “50 mile high club”).
“Achievements are a similar concept, yes… complete some particular task, unlock an achievement. The little details may vary a bit.”
“They’re on a player level, not a per-Sim level.”
