There are many alternatives to The Elder Scrolls for Windows if you are looking for a replacement. The best Windows alternative is Fallout. It's not free, so if you're looking for a free alternative, you could try OpenMW or The Lord of the Rings Online. If that doesn't suit you, our users have ranked more than 50 alternatives to The Elder Scrolls and loads of them are available for Windows so hopefully you can find a suitable replacement. Other interesting Windows alternatives to The Elder Scrolls are World of Warcraft, Guild Wars, The Elder Scrolls Online and Dragon Age.
As seen in the description, OpenMW is intended to be only a remake of the game engine. It isn't an alternative game, persay.
