The web museum of Paris can be a good way to spend a few hours. Thousands of famous paintings can be viewed online, with descriptions of the artists that painted them. Art is grouped by theme, as well as period for easy browsing. Gangsters.org is the place. Listed in alphabetical order by letter, hundreds if not thousands of websites are listed and linked containing just the classic game you are looking for.
All games listed are 'abandonware', or games that are no longer sold in the stores and hard to find.
Have fun finding games from the old days of Atari, Coleco, Odyssey, and the arcade at the mall. They are eventually collecting 6 billion drawings to represent the population of the world, and printing each and every one in a volume of over 12,000 books. They will add more each year to represent the growing population of the world, and eventually put them on exhibit for display. If you want to have a little fun, and 'artificial intelligence' intrigues you, click on over to the 20 Questions website. An artificial 'bot' will ask the questions as you go, trying to guess the item that you have chosen.
