Also, another correction: PEGI 7 forbids having violence between characters, but doesn't forbid having NPCs just walking around.And no NPC is due PEGI7 rating.
All this story about PEGI is a complete misunderstanding.
PEGI 7 forbids non-odyssey players to join ground battles in Odyssey...but doesn't forbid Odyssey owners to get back into 4.0-Horizons, which has a lower rating.
PEGI is a problem when going upwards, not downwards.
