"There have been thousands of PC games released in the past few decades but let's be honest: Most of them are not that original. Oh sure, some are professionally made and even entertaining to play but in the end very few bring anything new to the table.
There are some games, however, that attempt to break the envelope of normal gameplay and take things in new directions. Sometimes these games are big hits. Other times the ideas are used and refined by other titles even if the original game wasn't a sales success. These titles influenced many other titles since their original release.
Big Download has decided to give our picks for the top 20 most influential PC games of all time. These selections are not necessarily the best selling games ever made or even the best from a developer's point of view. However they all have elements that were original and/or popular enough to see their designs used in many other games. We are counting down from 20 to 11 today."
