I'm planning out a game that requires multiple users and I was wondering if there's a way to fire up multiple instances of the iPhone Simulator. I didn't see anything in menus or in Google search results, but I just wanted to make sure I wasn't missing anything.

As near as I can tell, not only can you not have multiple instances of the simulator running, but when time comes for actual device testing you can't have multiple instances of the debugger running either.
This means to do multi-device apps, you'll need to have a single Mac assigned to a single iPhone/touch device (or simulator instance) each running your app.
I've started looking into whether VMWare or Parallels can somehow be brought into this, but there's not much that can be done without hacking the OS.
I suggest filing a feature request with http://bugreporter.apple.com.
Another option (albeit probably overkill) if you have a Mac OS X server license is to virtualize an instance of Mac OS X Server, and run a second simulator in the VM.
Hmm...I don't think you are missing anything here. As far as I know there is no technology within the SDK that is able to emulate multiple devices -- though that would be a useful feature to have. I think your only options would be to get a second iPhone OS device, or get a friend who also has an iPhone OS device to let you use it for testing.
In XCode 4 you can run multiple instances while having both be in debug mode.
What I did was create a duplicate of my target and ran both the original and the duplicate. If you're using the output window you can toggle which output you are looking at.
