I also remember my friends having Age Of Empires 2 and Lego Rock Raiders and always wanting them. I recently found an old copy of Age of Empires 2 in our house that I've never noticed before and still haven't gotten around to playing it. As for Rock Raiders, I'm debating whether or not to try and download it somewhere since I've heard it's abandonware now.
