It's better to have completed 1000 imperfect games then spending your whole life trying to create one perfect one, because that will never happen. People will still love the imperfect games and get enjoyment from them even if there are flaws. Also, by the time you get to #1000, you'll be astounded by how much you've improved just by doing and finishing and releasing.
Don't pay much mind to those who heavily criticize, it'll always happen and often it's more a personal issue than one with you. Take what you need from complaints and pay most attention to those with opinions you respect (and even then...a grain of salt, they are different people with different experiences from you and you might have your own creative language.)
