I knew my personal PC game icon (and best anti-hero ever) Guybrush Threepwood would already have been mentioned when I enter this thread and I knew it would be either shio, dawve24 or gurok.
So I only have to add that a more suitable picture of Guybrush is in my sig (3rd sprite for those who are not familiar with Monkey Island).
Glad to see Sam & Max, Roger W., Gabriel K., Larry L. and Lord B. already mentioned as well. This thread warms my heart.
For a moment I thought I throw in Indiana Jones, but he already was an icon before ”Fate of Atlantis” and one legendary PC game alone doesn´t qualify him to be called a PC game icon.
