Enhancements You Can't Live Without:

• ATM Deluxe
  Adobe has really made this product something you cannot live without.
• Default Folder
  If you are not using default folder, you are wasting lots of time. It is a very affordable shareware program.
• FinderPop
  This program allows you do almost anything you want with contextual menus. It is incredible and FREE.
• Prestissimo
  Get rid of smart scrolling and move to really smart scrolling.
• SnapzPro2
  Create movies of what you do on your mac. Great for training.
• TechTool Pro
  Fix your mac.
  

Web Site Tools Programs

• BBEdit
  Great HTML & TEXT editor.
• Interarchy (good FTP program)
  Interarchy is so much more than a good FTP program. If you run a server, this thing can give you so much information on your traffic.
• GoLive
  It is THE BEST tool for website creation. It also has the fast FTP that I have ever seen.
• Stuffit Expander & DropStuff with Exapnder Enhancer

Great Games

• Bungie the commercial Mac game masters. Alas, they have been bought by MicroShaft. But you can still pick up their latest creation at GODGames. ONI is really nice.
• Ambrosia has a ton of shareware games that are all great; here are some of the ones I like the best.
