A few things I need to be upfront about:
1. A little anti-religion in the game....its a bit hard at times to ignore it.
2. Sometimes you will get stuck...I got stuck near the end of the game and gave up...after playing nearly two days straight it was time to see the wife again :-)
Assassin's creed 2 is nothing like it's original predesasor. You still have the same old Desmond miles storyline going but you have a diffrent ancestor. Your ancestor is Ezio Aditore da Firenze. Now the ancestreal gameplay is about 45 percent diffrent. Instead of investigations you have soryline missions. And also you have a money system. You can get money in a variety of diffrent ways. Earning it in special errands, stealing it, getting it in the villa's income, finding it in treasure boxes hidden everywhere. You can use the money to get weopons, medicine, poison, and armor. you can also use it to repair armor, hire teams, and bribe heralds to reduce noteriety. As you get more wanted in a city the notoriety increases. You can reduce notoriety by bribing heralds, tearing down wanted signs, and killing corrupt officials. You also have a new variety of assassination techniques. Air assassination, my favorite, double assassination, and hang assassination. There are also new cities. Florince, tuscany, Monteragon, Venice, and Rome. Just as an added bonus they also added the feature of swimming.In my opinion this is a very great game.
