Portable BYOND

If your lifelong wish is to make computer games and enjoy them along with other players, rejoice since nowadays there's a huge selection of software that can help you pursue your dream.
Portable BYOND is one of the applications mentioned above that not only serves as a development platform but also lets you host or join other multiplayer games as well.

Portable tool

This app doesn't need you to install it on the target computer, as it is portable. This means that you can enjoy its functions by simply unpacking the archive it comes wrapped in and launch the executable in the "bin" folder.
More so, it won't tamper with your Windows registry entries, nor will it create additional files or folders on your computer, unless you explicitly tell it to.

Two tools in the same box

As stated earlier, Portable BYOND can help you develop simple multiplayer games that can be played online but enables you to play other games, created by community members just as easy.
If you feel like creating new content, you can use the "dreammaker.exe" tool, where you are provided with everything you need to kickstart your projects. However, if you're more interested in playing the games, just start the "byond.exe" executable.

Play simple online multiplayer games

Once you launch the BYOND app, you'll be greeted by various games, neatly organized in a virtual database. Selecting each title will let you launch the game, read a short description of the item, as well as view comments and related content.
Exploring your options can be made intuitively, as every entry is displayed in a different tab so that you can quickly switch between your selections.

Comprehensive game maker and multiplayer online gaming platform

All in all, if you're looking for a tool that combines game-making and game-playing in a convenient manner, you might want to try Portable BYOND. It requires no installation, its interface is simple enough to be used even by novices and the community content is enough to keep you busy for a while.
