This is kind of a tweak on the once-in-a-while favorite apps questions (my top 10, program closest to perfection).
Why is this relevant?
- I've had a tendency to download, test, and evaluate TONS of programs that make very minor changes to minor issues. At the same time, I've been extremely satisfied over time with all the work I've put into GIMP and LibreOffice, the energy I put into them having paid off many times over. Maybe you have a program that was a little odd or had a learning curve that you now use frequently?
- What's entertaining and involving are more than just games. What programs really occupy the mind? The Powder Toy is part game, part experiment, while ArtRage got me making all sorts of creative stuff. If you list a game, it should have a high replay value.
