I'm sure you'll agree that's a-given...considering a lot of good games have been released since then. Such as games from competitions they've had so far. There are decent, dedicated projects in progress like Geisha House and Pirates of Port Royale - they've been in progress for a long time because the developers have normal lives to get on with and their projects are big.
Failed projects tend to come either from a lack of perception or something getting in the way. The of perception can come on your skill level, what you've got availible to you or the time you have to give on it. Smaller, simpler projects come out more often - the 'Nutt' games scored well with forum dwellers because the concept was simple enough for the person to focus on programming. If, like me you're one of those attempting to tackle all elements on your own, then there's little hope for you until you have a toolset you can work with successfully, are able to stick at it and can cope with the work.
Other projects are WIPs and you can't expect them to have a spotlight in the finished projects area.
