I got GTA IV in the beginning of 2009 on PC but I couldn't get it working because my PC couldn't handle the game, but I kept it "just in case".
Then I forgot about it and finally got it during Christmas of 2010. I was so happy and amazed that I rushed the game unintentionally, but I had some incredibly great memories from it .
Some times after, I learned that EFLC was already in stores, so I bought it in mid-2010 and played the sh*t out of it like GTA IV .
Then, I finally got a new PC that could handle GTA IV with its DLC, and I still play it from times to times .
