I bought a 360 from a co-worker who got it last Xmas and rarely played it (apparently his girlfriend thought he was much more the gamer than he really is.) Came with LEGO Indy & Kungfu Panda and he also had GH: Aerosmith (which, based on his gamesaves, is the only game he played when he did play it.) I decided to finally pick up a 360 to play Batman: Arkham Asylum which comes out in a month (I wanna get the demo that I've played at Fry's...hoping it gets released this weekend following Comic Con.) Anyhoo: 1) He has a gamer tag created, how can I delete it (I checked the 360 KB but it returned an error every time I tried to get an answer about this, despite this being a linked question)? 2) Is there a way to reset the console to factory defaults? 3) As I'm a new owner of a previously-owned 360 do I still get a free XBL Silver account? I don't know how much online play I'll ever do so I don't necessarily need to go "Gold", plus I'd have to shell out the bucks for that pricey wi-fi plug-in.... 4) ...is there a cheaper/reliable wi-fi plug-in other than the "official" one? Is that controller-typepad a worthwhile add-on if I do go online with my 360? Thanks for any help/advice you can impart.
