Game has many type of quests. Talk to someone or any npc, kill specific enemies, reach area, find quest item from enemy and bring it to someone, find normal item from anywhere and bring it to someone, kill enough enemies from specific spawnarea and that area will be disabled after completing quest. If quest type is mainquest it cant be aborted. But if its random quest and then abort or reject it when npc offer quest. Then there will be 10 minutes cooldown until can get new random quest, so player cant find best random quests. There is repeatable quests too. And every quest can have prerequisite quests which need to be completed before player can get that quest. And every quest can have world changing effect when completed, I can choose world tiles what change to other tiles. And there is questlines, mainquest is only one big questline.
NPC have green line around him if he has quest offer.
Some npcs can have rumors, double clicking them show rumor window if they have something to say. Rumors are always useful, they can give tips or tell where treasures might be.
