We've spent the week talking about Reality vs. Game Systems. Today I'm curious how much realism do you allow into your games? Obviously we're talking about a hobby with elves, magic, grand space ships, and turn based combat. But beyond the confines of the rules and the game, how realistic do you portray your worlds?
Do you bend reality for rule of cool? Do you bend mechanics for what is realistic? If a PC puts a gun to someone's head and pulls the trigger, is the target dead or just taking the weapon's damage rating?
I tend to run grittier (read: more real) when it comes to actions and consequences, but draw the line when it comes to people exploiting modern science for results, unless we're in the modern world. The way I figure it is that if you can literally talk to the mountain to get information, you don't then get to fall back on how our physics work. Yes, it's similar, but on a macro level. Not a micro one. As such, stone doesn't float (regardless of displacement and engineering because that math doesn't exist) and you can't necessarily make an explosive device by throwing magnesium into the river because you probably don't know what magnesium is.
Beyond that, I find keeping things grounded in the similar can help with immersion and I tend to like it. How about you?
