Begin two game clients together?

Is there a program or way to begin two game client “mmorpg” together?

1) Count backwards from 3

2) When you get to 0, launch the game.

As for automatically doing it, you could write a program that communicates between the two computers with one being the server application, the other being a client. The server application would send a request to the client and ask it to begin the game. The server would also start the game. As for a language, most languages have the capability to call “system” operations.

Now the question back to you is why are you worried about starting two MMORPG clients together? They each have to go through an authentication process and having one complete before the other shouldn't be an issue to you as an end user.

** Edit **

Many applications tend to check to see if an instance of the application is already running so you might find that you can't run more than one. I don't think you’ve an easy way of forcing a process to a single CPU since the OS is optimized to try to spread the balance of processing between the two CPUs (note, this doesn't mean that a single process will use multiple processors, but rather that the first process could take the first CPU and the second process would take the second CPU). If you want to limit a process to a single CPU, think about setting up a virtual machine (VM) that is limited to a single CPU. Inside that VM, run two instances of the application. This won't bypass the check that some applications make to only run a single instance, but it would get those that would normally take the next CPU onto the single CPU in the VM.
