When exploring Jerusalem, it can become boring quite fast. The streets seems empty and not what you would expect it to be in a most likely busy capital as Jerusalem.

Adding people and animals in streets, houses and in backyards would make the game more realistic.

And i guess the streets would probably be more dirty, giving the time period didn't have sanitation as we do today.

Furthermore it would be nice to be able to interact with more NPC's than those in the main mission.
