The game Ares started as a smaller, simpler game. It's inner workings were not originally meant to be generally accessible. It had a somewhat organic development, and at times ugly things were done.

Hera does much to hide the ugliness. There are still aspects to editing Ares scenarios that are less pleasant than they could be, but Hera is a very powerful tool.

While you don't need to be a programmer to use Hera, you do need to be patient and technically inclined. ResEdit experience is strongly recommended.
