How can I plan lan games with VM ware?

VMware Fusion is a Virtual Machine software program. It creates a software environment that mimics physical hardware so you can install different version of many other operating systems into what is called a Virtual Machine.

Once you install VMware Fusion you also have to install a version of Windows into a Virtual Machine, Software that emulates, mimics, physical hardware for Windows to run on.

Without installing a version of Windows into a Virtual Machine you can't play that game.

In the Virtual Machine network settings set it to Bridged. It is more than likely set to NAT now which will put the VM on a different network than what the local LAN is using.
