I think having character classes you select at the beginning would add a cool wrinkle to the game, and have an effect on the way people play, since each one is tailored to a specific playstyle. Here are my ideas: Survivalist The survivalist is a character decked out in flannel, jeans, and a hunting vest. Survivalists get bonuses to inventory space and crafting. They can craft better items, such as cooked meat that restores more blood. Soldier The soldier is a character wearing full combat gear. Soldiers get bonuses to firearms proficiency and vitality. They also have a "Soldier's Intution", which is basically the dots on the edge of the screen that are already in the game, just limited so that only soldiers can see them. This allows them to have a better sense of where potential threats may be coming from. They are also more accurate with guns and heal a lot more quickly. However, due to the weight of their gear, they move more slowly. Athlete The athlete is... well, they're athletes. Wearing light jackets and cargo shorts, athletes' hunger and thirst meters drain a lot more slowly, and they also are more proficient with melee weapons and can run faster. Bureaucrat The bureaucrat is a character in a torn-up shirt and jacket. Bureaucrats spawn higher quantities (not quality) of loot, and are balanced in all other areas. Hopefully none of these sound too unrealistic or game-breaking.
