I got some Big vibes from playing “Black and White” back in the day. You’re a God to bronze-age villagers, and you sorta-control a semi-autonomous giant animal pet/ avatar, so that’s automatically giant-ish. But the most manifesting way is that your way of interacting with the world is as a hand, and the world is complete with physics, you can toss rocks and villagers - or, what I tried to do most of the time, you can gift them with food and wood by harvesting resources for them.
To conquer enemy villages, though, to become their God, tossing a boulder into their town square was an extremely fast way of gaining their belief.

In the story I wrote of it, the giant was just too focused on the humiliation and domination of his rival to let the pain stop him. He decided afterwards, though, once the adrenaline wore off, (and my narrator stopped telling the story), that it was a one -time event.
