There's no store near me that rents video games.
The major complaint that people have about the game, is that it's repetitive.
What will happen is-
-You get told to go to one of the 3 cities to do an assassination
-Go to the Bureau in the city to get more info
-Climb high viewpoints to clear spots on the map and locate informers/pickpockets etc..
-You can either quickly do 3 of the Assassination related missions, either Pickpocket, Eavesdrop, Interrogate, or helping a fellow Assassin either pick up flags or take out a few people.
-Or you can get all the view points, do all the Assassination related missions, do all the Rescue Citizens, and earn more health/help from the city
-When you're ready you go back to the Bureau, and start the Assassination mission. Each one of the 9 is different scenerio and are all pretty fun. Your goal is to either take the target out stealthily or kill everyone including them.
-After you kill them, you escape back the the bureau and then go back to the Assassin's place in the mountains to get a new assignment.
Lather rinse repeat.
If you can get over doing the same missions over and over again, the rest of the game is superb. Which is why a lot of people, including myself, really like the game. People like Jerry! obviously don't.
