I was considering buying another game card so that I could have a main town and a cycling town, but money is really tight considering I just went to a concert last night and spent well over $150. I have a friend who plays ACNL, and so does her brother. Would her town be transferred onto my DS? Also, would this affect her town that she has on her own system? Lastly, would this affect my first copy of the game? We were considering just swapping game cards when we saw each other and cycling from each other's cards, but we're both worried about our towns. If someone could please answer these I would be so grateful
