Vikings actually weren't just warriors they mainly farmed or did other trades when not raiding. Add professions to the game to further develop the co-op nature: Farmer - collects more food from plants Lumberjack - lower stamina when chopping wood or does more damage when chopping wood Carpenter - lower cost for building with wood and reduce cost to make/upgrade items at the workbench Mason - lower cost for building with stone Chef - reduced cost for making advanced foods or more output for the same cost Brewer - reduced cost for brewing or more output (whichever is easier) Hunter - more drops of food items (raw meat, neck tail, etc.) Blacksmith - Reduce cost to upgrade and make items at the forge Expertise - as in weapons Pick a weapon category - use less stamina and/or do a very slight bit more damage (we don't want to unbalance) and/or reduce weapon wear. Also to prevent people from switching at will to just gain the benefits this should either be a one time selection or time based like cannot change either for 25 in game days.
