If you remember the old days before video games even had graphics, there were popular text-based games where you had to type commands to tell which direction to go and what you were going to do such as Attack Troll or Go South. While text-based games are considered way too old fashion to sell as games any more, they can be used to create interesting games for fun. One such game is called Cat Petting Simulator.
The goal of Cat Petting Simulator is to describer a cat near you and then wait for your commands to play or pet with that cat. Just type in commands and now you can pretend to play with a cat at work without actually bringing your cat to work or displaying pictures of cats on your computer screen. With the Cat Petting Simulator, you an get nearly all the benefits of a cat without having a cat physically near you anyway.
