Commercium is an open world, multiplayer sandbox game, with an emphasis on freedom of choice & role play. You can build houses, buy weapons and decorations + furniture, run for mayor to change the town rules & taxes, work as a police officer, farmer and more. Almost everything in your home can be customized. If you want to steal other people's belongings, you can do that too. The choices are all yours.
Commercium is currently in development, and focused on home building. After home building is solid, focus will move towards guns, hunting and vehicles, until the game is a complete package.
