It's not ideas that are a problem. Ideas are cheap and everyone has them. It's the time and effort that goes into making a game that is the hard part. The fact that we're making it for such a small audience doesn't help either, since the pay-off is quite small (but special in its own way).
What we really need is ways to make things easier. The tutorials from LX.NET are a great example of something that will help a lot of developers out. The developer/flash cartridge from Lynxman is awesome. CC65 is making it a lot easier to step in as well.
For example, one of the things I'd like to see is more information on Audio (hoping LX.NET is working on some tutorial material for this).
