Lol. It really wouldn't.
Elder Scrolls would work, they could even keep the same theme as the games - each series from a different era, and a different province of Tamriel. Mass Effect could work in theory, but there have been several Sci-fi space shows this century so far, I doubt we'd need more. Plus the effects budget would be prohibitive.
However, if money wasn't an issue and effects could be done properly ... while Uncle Mike is right that Horizon Zero Dawn itself doesn't quite have the meat for a TV series, the back-story from the lore that's in the game could make for a pretty tasty prequel mini-series, while also standing on its own without ever needing to even once directly reference the game itself.
