Take me with a grain of salt because I'm pretty sure I'm in the minority..

Why is it so important that line of sight be symmetrical?

In the following example (copied from another post), I would consider the @ to be both hiding behind the wall and peeking around it. So the @ should be able to see most of the hallway, but it should be pretty unlikely that the M would notice the @. This would involve having stealth as a factor in line of sight but I think it's much more realistic that way.
The problem with assuming that the player and monsters always take the part of the grid in the middle is that any player or monster with sense is going to try to keep as much of their body as possible out of the line of fire (which should be the same as LOS).

My old variant DaJAngband: (defunct and so old it's forked from Angband 3.1.0 -I think- but it's probably playable...)
