Nifty little tip...

[Maakt Droog]

Why do you have to show exploits of the game engine? A bug is a bug, this is an exploit.

This strikes me more as an element of understanding the information that is presented on the screen, whereas exploiting the game engine comes up more in the form of getting units to do impossible things. (I seem to recall on a board somewhere that there was an intense debate about the "gamey" positioning of guns with respect to a hill crest which was considered exploiting a bug in the game engine, but I could be mis-remembering....).
