1) What is the main difference between the 20gb and 120gb? It's black, and you can store 100GB worth of more data, which can have anything to music, movies, pictures, saved games, or just data. 2) Do you have to pay a subscription or something to use Xbox Live? Yes, here are some prices. Note: For buying an 360 you get a month free of gold membership, it activaces when you sign up for xbox live. 3) Does the xbox just connect directly to a normal internet connection? Yes. 4) If yes on question 4, can I use a wireless network? Yes, you need to buy a wireless Adapter though, they run around 80-120 dollars. 5) Does the xbox now come with that ugly extra fan thing that is needed to stop it from overheating or do you have to buy it seperately? It's made by nyko, so you have to buy it seprate, but I wouldn't buy/use one as there is ton of reason that it causes more harm then good. You Xbox shouldn't over heat if you put it on a flat surface, with ton of vent space. Games: - Halo 3 - Assains Creed - Call of Duty 4 - Fable 2 - Mass Affect Extras: - Charge and play kit or Quick charge kit - (I like the quick charge kit) - Extra controller (wireless) - If you want to play with friends - Wireless head set - (Amazing difference to the wired one) - Live membership Tips: - Down move xbox when disc is in - Use button to close tray - Keep horizontal - Dont put on rug (use hard cover book if you have to) - Delete all videos, demos and games when you first start you xbox up, this will give you a good 2GB of free'd memory - (Do if you don't buy 120GB) - DO NOT BUY Arcade I hope this helps! Happy gaming. :D
