Skyrim is the longest running entry in the whole series. Originally launching in 2011 and having multiple re-releases over the years, it's been going for more than a decade, and it doesn't seem to be slowing down either. While The Elder Scrolls 6 is said to be in development, it's likely to be a long time before fans see the next installment. Luckily, TES5 has a lot to see and do, and with the modding community constantly releasing new content, its longevity is growing all the time.
