Actually Starcraft does still work under 10.2, just that there is a small glitch with the config dialog box. If you boot the app and the dialog box comes up at all, Starcraft will die.
Here is the workaround: When the config box comes up, set all the configurations and check the box "don't show this again". Then hit OK as usual. The app will crash, but relaunch and enjoy. Every launch from then on out will be just fine n' dandy, as long as you don't hold option to bring the config box up during launch.
