Indeed market competition does great in encouraging developers into creating better products. This is because as market competition gets intense, the developers think of more ways to gather a stable community of patrons and they can not do this if their project is not interesting enough hence, they will fall behind and fail. In real world, monopoly in a certain industry only leads to an institution gaining more control to the consumers because they will dictate the prices and the consumers will suffer. Just like in games more competition raises the stakes as well as the money that can be earned so it is a positive thing.
