Good morning I slept terribly.
Scrolling down I saw mention of Lia playing Dead Space. U think this is a genuinely good idea. It's not overly long and from what we've seen in her Souls play throughs she gets visceral satisfaction from brutal kills. The Stomp™ is literally made for her.
BioShock 1&2 might work too though it's not quite as viscerally satisfying.
Finally, HOTD on hardest difficulty. It's one of those games designed explicitly around the idea of transforming fear into euphoric rage.
