People don't buy my games because I'm a poor alone developer, they buy them if they are fun.
I don't buy software because is done by a small team, I buy software that I like or need.
While I agree- I think the issue I am constantly reminded of as an independent developer, is that most players have their expectations defined by games created by larger companies. Those are the games people are force fed and taught to accept, generally speaking. So it's not necessarily about what is "fun", because very simple things can be fun. The issue I see is a type of expectation a person has and whether what they see lives up to it or not, and this expectation they have can be completely biased and unfair.
Unfortunately for the small developers, they can't do much about that- they have to learn to accept the reality of the consumer base, and make an extra effort to show why they should be supported or considered. This is what I find myself facing currently, and learning to overcome.
I'm sure this applies similarly to tool makers, like scirra, or any small team.
