A company logo should represent a company and be identifiably in an instance.
Sometimes the logo would also reflect the vision and ideals of it's members.
Game companies, being a very young branch of business, often had very artistic logos.
That is why I reserved a whole section to these logos.
It is especially interesting to see the changes that these logos went through over time.
Sometimes with just minor changes and updates, some other times a company would completely change it's logo again and again.
