In a nutshell, this website advocates the adoption of the label persistent browser-based game, or PBBG, to describe browser-based games that allow progress over multiple playing sessions.
The PBBG definition is quite broad. The PBBG genre encompasses games of all traditional genres: role-playing, strategy, sports, simulation, and so forth.
PBBGs may be single-, multi-, or massively multi-player games. However, since an Internet connection is required to play, most developers incorporate massively multi-player and community elements into their PBBGs. A multi-player PBBG can be referred to as a MPBBG, but multi-player game play is usually assumed.
PBBGs may be text-based, or they may take advantage of browser plug-ins such as Flash or Java to create a more dynamic game play environment.
The PBBG definition is device-independent. In particular, a persistent game played within the web browser of a cell phone or other wireless device is still a PBBG. Such a game may be referred to as a mobile-enabled PBBG.
A PBBG is not the same thing as a MMOG (massively multi-player online game), generally speaking. There is some overlap, but MMOGs include games that are run as an application on your computer. Application-based games do not have the portability that PBBGs do, because you can only play them on a computer that has the game installed. Think of PBBGs as a subset of MMOGs -- those that are browser-based.
A PBBG is also not the same thing as a browser-based game, generally speaking. Browser-based games include arcade, puzzle, and poker games which are over as soon as you move your browser to a different web page. These games lack the longevity of PBBGs, where progress is made over days, weeks, or months. PBBGs are a subset of browser-based games -- they are persistent browser-based games.
There exists a vast collection of online games that are often referred to as browser-based games or MMOGs, but which are really the intersection of both. The terms browser-based game and MMOG do not adequately describe this segment of the gaming industry. The PBBG designation is a solution to this problem.
Widespread adoption of the PBBG designation will:
Simply use the term PBBG. If you are a player, try searching for PBBGs using your favorite search engine. You will find many. If you are a developer, publicly designate your game a PBBG on your website. PBBGs will not be known as such until their makers and players acknowledge them as such.
The PBBG project has already accumulated substantial grassroots support -- the links page is a testament to that.
This website was created by a gaming and web development enthusiast. I have been involved in website development for about ten years, particularly server-side programming. I have been developing and publicizing what I now call PBBGs for nearly seven years, and have been playing them for even longer. I have created several games, as well as a large directory that specializes in PBBGs (I will not be specific - this website is not about publicity for me).
