Not only have we tried it, we also successfully released 2 mobile games ( Planes Control and 2 Minutes in Space) from zero to 4 million of players ( together iOS and Android) and opened a coworking for game developers And this all as a team of 2 people and without any investors or any marketing budget. We pay with our time, which is also money, it's clear.
Do not underestimate the importance of: - a polished game, no matter how simple it should be. - bootstrapped marketing.
