It's taken a lot longer than I had anticipated, but here's a tutorial that presents no less than 12 different ways to detect different types of collisions!

Once you understand using the collision techniques, you should be able to program the following types of games:

Graphical RPG (single player only not MMORPG)
Duck Hunt game
Shooting Gallery
Hidden Object
Mirror Picture
Railroad Tycoon
Road Race
And many more!

Attached is a .zip file that has:
> The tutorial in both Word .doc format and HTML
> The source code for all of the collision functions.
> Simple example code to see how everything works
> The solution to "flaxen's dilemma" (discussed in tutorial)
> A simple triangle game that starts out easy and later becomes frantic
> A puzzle game (see Point In Polygon Function.bas)

Update: 2009.09.08
> Have added a missing example program highlighting the "Point In Polygon" function.
> Re-named R2R.bas to "Rectangle To Rectangle Collision Function.bas" as stated in tutorial.

Thanks for the update

Attached is another version of the jig-saw puzzle provided in the last update.
This version is significantly harder than the last one

Here's 3 new collision types:

1) Circle To Rectangle Collisions
2) Circle To Ellipse Collisions
3) Circle to Triangle Collisions

Included are simple examples to see how things works.

In all 3 examples you move the sprite with your mouse to make the collision occur.

(NOTE: The Circle To Triangle function ONLY checks for collisions with the lines defining the triangle (including vertices), but not if the circle is entirely inside the triangle.)

The original Polygon Editor has a couple of minor mistakes, so those have been fixed, and have added a couple of minor improvements to the output data.
