In an older game, two opposing forces would close, and one side would always fire first. The unit that was first in the program's list of units. The decimated unit that was fired upon would return fire at it's depleted strength. No fun. Using the new multi-core, hyper-threaded approach, each of these units would be operating independently, and when in range would fire at each other simultaneously! Fun!
I could go on and on about this, but will spare you and get back to game development.
All of our legacy software is still available, and will be available for download on this message board, but support will be limited (even more so than it is now!)
