Zwift for me. Apple MacBook HDMI to a TV and ANT+ connection. I've been using it since it was in its beta infancy. It is more like an animated game but I like it. Lots of events with other riders, workouts and easy to design your own. I have used RoadGrandTours app which is cool because it is a real road vid game but the vid was kind of jerky and that bothers me. I think Rouvy looks interesting as well, tho I've not tried it.
