- Skill trees – Skill trees are one way gamers can play concrete story line that way they want to.
- Consequences (v1) – I love when games give the player options to choose from, such as you can have this item, but you with also get these other effects/items with it.
- Consequences (v2) – I also love when NPCs and other parts of the game react to what the player does. And example of this is relationship status with other factions in The Outerworlds.
- RPG – Gamers can really get into a game if they have the opportunity to chose their own path to follow.
- Restrictions – Games will often have restricting rules or objects in order to guide players along, or keep them from doing something wrong/stupid.
