You remind me my son, who also like this game. I can imagine to restart what you sis before makes a lot of fun and you are right, it is sometimes easy to get addicted to Video games, especially with new technological advantages and quality of game programs. Have a fun!
Yes, video games these days really manage to suck you in! I don't think it'll happen to me again now, because I have too many other things I want to do now. It helps to have other goals to keep you from getting addicted to one thing :-)
