Eternal Trails is a 'work background' exploration-lite game. Hands-off exploration on horseback, exploration without too much effort. Your horse likes to self-explore, but you can take the reins at any point if you wish.
Designed to run in a small window, it's a perfect work companion. Your horse will automatically explore incredible and varied vistas, all you need to do is watch whilst you work. No sound, no heavy mechanics, just stunning views and sunsets.
