No matter how many or what kind of bullets you shoot are your friends, you'll simply never kill them.
Depends on the game sometimes you kill them sometimes you don't or you just wound them.
Melee attacks not hitting walls
You can destroy certain things and they come back. Grass, enemies pots etc
You don't shoot the person always in the cutscenes and let them do a long boring speech then get in their high powered weapon
Security for homes and certain locations suck
You never seem to get tired throughout the journey
Corpses can get stuck it walls and other objects
No matter how much time you take the villain usually waits for you
Falling generally does a set amount of damage or none no matter the height
You can time travel to redo quests certain times
The weather usually never changes no matter how much time passes.
Your own weapon can go through your body same with then enemy
You can buy a endless amount of items from stores usually despite them only having so much space and so many items on display
Despite being cloaked or hidden bosses see you clearly when regular people cannot.
Hardly anything degrades or gets rotten over time
People generally ask you to do something before giving you something despite you being a hero who is trying to save them or the world
You always have a way to get out and never get stuck like some unfortunate NPCs.
You hardly ever if not ever get dirty
No matter how much you drink or eat you hardly ever throw up or die from alcohol poisoning.
