Almost universally computer game covers are shit. The absolute worst.
In my effort to illustrate basically everything I'm doing, I have done two covers for the computer game which has nearly destroyed my life since it came out: Modern Warfare 2.
There is a level in the game where you take part in a terrorist attack on a Russian airport. That was the moment in the game that stuck with me, and that's what I wanted to put on the cover. I was trying to boil it down to graphical symbols (bottom one), then I did the slightly kitsch version (top one), which maybe I prefer. I don't know.
