If making games were like spinning a roulette wheel this might be true. Making games is an art though, and part of that art is learning how to make really great experiences for the player. You can't do that without a focus on quality over quantity. Especially as an indie-developer with limited resources, what exactly are you going to make that anyone is going to care about if you're constant releasing half baked stuff and starting new projects?

You're right of course -- to a certain point. Half baked products will not succeed. Still, law of diminishing returns is in full effect here. When to launch? When is the MVP ready? I don't know the right answer.. Some say earlier than gut instinct would compel.
