Im making an Indian Airport, and as i understand im the only one doing it. Its a big and important airport of a Tier 1 City. But unless its on the marketplace, its not really worth my time. i dont trust selling it on 3rd party sites.
Quality wont be an issue because i have the skill that match the quality something say like the CYYZ from flytampa [i have been selling game assets for some time now].
But if its no accepted, there no point. But i dont also see any big devs like orbx or even anyone else making it.
Some interesting comments from Jorg on the dev Q&A today, they are certainly aware that there is room for a lot of improvement allowing dev access to the Marketplace. However he also said that they do monitor the online chat around upcoming projects, to see what people are really looking forward to, so although there isn’t really an answer to your question, your first step would definitely be to get some work done on a project and get the word out online.
I am in a similar position to you, thinking that it just isn’t worthwhile completing a project if I’ll never get access to the marketplace, but with the upcoming WU12 New Zealand, I am rethinking this.
Next month will be the second anniversary of my application…
