Speed Demo Archives presents Awesome Games Done Quick 2015!
It's a week long marathon of awesome games played quickly. It's tons of fun to watch all the classics you may have played as a child as they get cleared by pros who exploit every trick in the book to beat the games in record speed.
It costs nothing to watch this amazing event, but if you like what you see going on, you should make a donation to their efforts. The donations enter you in drawings to win gear and cool crap that they are giving away (depending on the size of your donation and when you make it) and allow you to influence certain aspects of the runs that are being made, all while supporting the Prevent Cancer Foundation.
To see when games you love are being played, check out the schedule at https://gamesdonequick.com/schedule
and disable your adblocker if you are going to watch (so far as I know, the revenue from ads viewed on the stream also goes to support the PCF.)
