If there was any confusion about the nature of Rise of the Tomb Raider's Xbox exclusivity, it wasn't Crystal Dynamics' intention, the developer has said.
In a Rise of the Tomb Raider FAQ posted to the game's official Tumblr, Crystal Dynamics was asked why Microsoft, Square Enix, or Crystal Dynamics itself didn't say upfront that this was a timed exclusive, and why it used indirect language.
"We certainly didn’t intend to cause any confusion with the announcement," Crystal Dynamics said. "The Microsoft Gamescom stage was a great place to make the initial announcement, but not necessarily to go into details."
When it was first announced at Gamescom that Rise of the Tomb Raider was exclusive to Xbox One and Xbox 360 in holiday 2015, there was some question as to whether this was merely a timed exclusive, which would allow the game to come to other platforms sometime following its Xbox debut.
