Video games are one kind of simulation we generally engage in, and the answers to these kind of questions are because they're enjoyable background or optimized for gameplay rather than something else. Games like half-life 2 spend a lot of time simulating really boring physics so that they can exist for the few situations they're actually kind of interesting. Lots of games have worlds where every single entity is hostile to the main player or damages them in some way.

If we're in a simulation, we can't discount that we're being simulated in a specific way for non-obvious motivations.

The quantity of extra computation isn't comparable. Half-life 2 may simulate a few objects falling, but it doesn't simulate e.g. the Sun. Which, in our universe, is a computation trillions of times more complex than everything that's 'interesting', at least from the point of view of simulating intelligent beings.

You're ignoring the possibility for shortcuts. Half-life 2 ALSO simulates the sun! It simulates it as a spot of light in the distance in the game. Similarly, the gravity and friction and motion simulation is hugely simplified compared to reality. If the sun works the way it would work in what we understand of physics, it would be extremely complex. But the same doesn't hold if it's a simulation.
