I feel like it's hard to launch a game as an MVP. You can try it out, but actually selling it without having all the aspects of the game (sound, graphics, performance, etc) might be hard.
It seems that this is the purpose that Steam's Early Access program fulfills. Players know well that the game is unfinished, but there is still enough there to explore. Users even pay for this early access and then they provide valuable feedback to the developers. Sounds like an MVP to me!
