Or why being consistent is so damned important
There is an obvious difference between real-world logic and in-game logic. We know that in the real world, you don’t heal from bullet wounds just by picking up a first-aid kit, or just by sitting behind some cover for nearly half a minute. We know that you can’t run for hours on end with fifteen different weapons strapped to your person and we sure as hell can’t cut hair longer.
Yet we accept these things in games –even ‘realistic’ ones- because when you’re playing a game, different rules about what makes sense and what doesn’t apply. It’s part of the entire fun of games.
