The Atari 2600 game suite was originally released in the 1970s, and was a big hit at that time. It involves several games that are played by users using the keyboard to enter actions. These games were a big hit back in the day, and inspired many computer game players of the 1970s and 1980s, but are considered too primitive by today's video game players' standards. However, they are popular today in the RL community as a portal to games that can be trained by RL agents.
