An important factor a game needs is Jobs. Jobs are tasks that NPCs assign you and you do the NPCs a favor. Here are the different types of jobs a player can be assigned:
-Giving materials (i.e. Give me 100 light shards)
-Craft me a weapon (i.e. Craft me a Sudaruska)
-Kill me monsters (i.e. Kill 20 dreadnaughts)
-Kill me rare monsters (i.e. Kill 3 soul jellies)
-Give me crystals (i.e. Give me 100 dark matter)
-Give me a heated equipment (i.e. Level 10 Swift Flourish)
-Show how you look with this outfit (i.e. Talk to the NPC while wearing a specific set of equipment)
