My friend has a problem. I wont get into the details but basically, he has a plane ane he wants to put a small hole into the center. He cant just make it transparrent in that spot because he eventually wants to import it into a game.
?
And you couldn’t answer him? Come on 
What you could try:
Make the plane, make a cylinder which will cut the hole. Select the plane FIRST the cylinder THEN. W KEY -> Difference.
Boolean operator will mess things up because a plane is not defining a volume, so you will get a plane with a portion of a cylinder.
Delete that cylinder.
Voilà!
What I would do:
Make a plane
Make a circle witht the center on une vertex of the plane. Join them if not already a single mesh. THe cyrcle vertex number should be a multiplus of four.
If this is not true already rotate the circle so that two vertices lie on the plane’s sides.
Delete the plane vertex which is the centr of the cyrcle. Delete 3/4 of the cyrcle. Join the nodes so that you have a plane with a quarter of a cyrcle chopped away.
select all nodes, SHIFT F KEY
mirror the quarter vertically & horizzontally to make a full plane with a hole.

My approach would be to use bezier circles then convert to a mesh. Very easy.
Right
but you have to explain him how to square a Bezier circle %|
Stefano
here’s how:
create two bezier circles and scale one a bit. then go into the edit buttons and make the bigger one poly. then delete control points until 4 are left and put it into a square by moving and snapping to grid (useing shift-s => selection to grid) each control point. then (if not already so) join the two using ctrl-j. that’s it!

Hello
An object to a game!!??
Add a plane, in Edit mode add a Circle (6 or 8 points is
a good number) scale it to the desired size and …just build faces
Select 3 or 4 verts and press F key
Bye

I like CurtisS’ approach.
A more complete description would be:
- erase [x] the default plane,
- add a bezier circle Shift_a > Curve > Bezier Circle
- duplicate it (Shift_d), and scale [s] it bigger
- rotate the larger circle 45 degrees
- press [v] to change the curve handles to vector handles
(If you are using it for a game, you may want to lower the ‘DefResolU’ setting in the Edit Buttons window [F9] to a setting of 4 to reduce the final face count; be sure to press ‘Set’ to make it take effect)
- Finally, [Tab] out of edit mode, and press alt_c to convert it to a mesh.
- To clean up the face arrangement a bit, [Tab] back into edit mode, select all [a] vertices, and press Alt_f to perform a beauty fill (Just distributes the faces more evenly).
Lots of different approaches, the above sounds like a lot of steps, but it really just takes in the order of seconds when you know what all (or most) of the shortcut keys do 
<Edit>
Actually, why not just apply a texture using the UV editor?
It supports transparency and works in game mode. Would seem to be the more economical approach.
- switch to side view Numpad_3, and rotate the default plane -90 degrees,
- press Ctrl_Left Arrow Key (to open a 2 window screen),
- In the 3DWindow, press Numpad_0 to enter camera view mode, then press [f] for face select mode, and press Alt_z to switch to textured view mode,
- In the right window press Shift_F10 to open up an image window,
- Press the ‘Load’ button in the header of the image window and browse to an image file on your computer (use the little gray button next to the ‘Load’ button, if you want to browse for the image file by just using the file names). Note: the image would need to contain an Alpha channel to have a transparent hole.
- In the lower window switch to the Paint buttons window (click the icon in the header with an image of a paint brush)
- In the center bunch of buttons, below where it says ‘Face Select’ change the bottom set of purple buttons from ‘Opaque’ to ‘Alpha’.
If the back of the plane will also be seen, press the ‘Two Side’ button also.
Now, in the 3DWindow, if you enter game mode by pressing [p], you should see the plane with the hole in the middle.
If you need more help, just ask.
