How to determine if you are an NPC? 1. Frequently bored, no main storyline quests. 2. Doesn't consume resources much, has no money. 3. Simple modeling, looks ordinary. 4. Only updates skins during holidays. 5. Low health points, easy to get injured. 6. Limited activities, often confined to a single area, restricted wherever you go. If all of the above apply, you can basically be sure.
