List of EZ to use game development systems

Some recommendations (from a mailing list) game development systems as teaching tools:

• StarLogo TNG:
• Stagecast Creator
• Squeak
• GameMaker.... scales from pictures to a BASIC(?) like language. I really like this one for teaching.
• Dark Basic
• blitzbasic
• GamesFactory 2
  
• Scratch an object oriented system from MIT media lab
  

Of course, I still think Flash is a really excellent system.
