Open Devtools = cheaper games (Score 1)

While I believe in the good ole 'if somebody has put effort into creating something, and you use/play it, buy it' principle, it seems to me that game dev costs would fall significantly if there were better/quicker game authoring tools around. There's a bunch of rapid development tools like Virtools, Quest3D, Radishworks etc out there that attempt this, but it hasn't quite reached the point where you can grab a 1K game authoring package with a decent 3D engine, physics, GUI driven workflow etc off the shelf they way you'd grab, say, Studio MX. Might be something the open source community ought to look into.
