The genre of arcade and platform games is both one of the oldest and the most loved of all computer PC games. This is because the whole market of PC online gaming was built from the ground up around basic arcade games from back in the 60′s and 70′s. In fact, the most played games online are often from the arcade and platform game genre because everybody loves the chance to play their favourite childhood game once again. For instance, there are plenty of online versions of Pac-Man and Space Invaders found around the internet world because of the high level of familiarity that the general public has with the games.
Of course, since the sixties arcade games have advanced quite a bit, so while you may recognize some of the old favourites on the PC, you may have to play them in a different style. You also may have to get used to a new theme, since many of the new PC games may have the same names that you know, but now have completely different plot lines. However, most people enjoy the new versions as the graphics are better and there are a lot more challenging or intriguing twists that keep simple arcade games addicting and interesting.
Additionally, the genre of arcade games also includes many task orientated action and adventure games such as Cake Mania and Diner Dash since there is no strict definition as to what constitutes an arcade game. Thus, sometimes you may find that there is a mixed bag of options when you start to browse through arcade and platform games.
