Linux fanboys, this one's for you!
Objective: Install and play my 12 year old copy of Starcraft 1
Problem: Windows 7, despite having its "compatibility mode" nonsense, could not properly display the game after installation.
Solution: While I didn't have the new system set up for dual-boot yet, I did have a few Linux virtual machines set up through VirtualBox. I quickly became intrigued by the thought of running Starcraft through "wine", the Windows emulation software for Linux.
The irony: I am using Windows 7 to run a virtual instance of Linux so that I can emulate Windows in order to play a game that is incompatible with Windows 7!
Did it work? Beautifully :-)
If you work on the "wine" program, I tip my hat to you...
