To elaborate, the original UFO: Enemy Unknown/XCOM: UFO Defence on Amiga and PC had a thing where, due to a bug in the code, EVERY difficulty was set to like Hard difficulty. Even SuperHuman. There was no difference.
Thought the game was hard even on Easy? You're right, it was. Thought it was too easy on SuperHuman? ...it was also this, yes.
Turns out, Wrath had the same issue until just now. ALL difficulties, due to a bug, were set to Outlander Difficulty, the hardest. lol.
