Telltale games notes that while Steam was their starting place, it lacked the sheer breadth of reach, particularly to casual and first-time gamers, that the Windows Store and UWP could offer. In short, the port to UWP was a tactical move to allow Telltale to find additional ways to get their games in front of a larger audience of players.
Steam has around 125 million active users, but Windows 10 already has more than 300 million active users, with this number set to rapidly increase over the next 2 years to hit Microsoft’s 1 billion target.
Telltale games note that porting to UWP also came with free ARM support, and that they already have a build of their story engine that could be used for Lumia phones running Windows 10 as well as future Windows 10 devices.
