Preferred difficulty for non-strategy games

[Quirinus]

But god, did that send us crazy or what. I hate the Library, with a passion.

Ugh, yes. That was my least favourite level too, I wanted to shoot that bloody annoying robot thingy out of the sky.

But whoa, Legendary was hard. I remember getting screwed up two shots from the Covenant Elite's plasma rifle in the very first level, and then giving up for a lower difficulty setting.
