No, the only thing that'll change is your gamertag.
Nope.
no it wasn't. Xbox > xbox 360 > xbox one
xbox 360.The Xbox 360 is the best as it can run games for both the Xbox and the Xbox 360.

No. (360)
No, you will not. All gamerpoints earned will stay the same. No matter if you were offline or online its on the profile.
No, the only thing that'll change is your gamertag.
No you do not. When you register a gametag with xbox live the gamertag is given a 1 month gold membership, but no points.
Unfortunately, gamerpoints can't be transferred from one account to another, even if you move the save file.
No, you have to either buy by credit card from your console, over the Microsoft website, or buy it in a store, ebgames, GAME and K-Mart are your best bet.
it means gamerscore acquired by doing certain challenges on xbox 360 called achievements
Most map packs are 800 Gamerpoints and need to be purchased via XBOX LIVE. Sometimes, there are discs out there for sale, but I highly doubt there are any for Halo 3. There used to be for Halo 2 though. Bottom line: Purchase from XBOX LIVE for 800 Gamerpoints. (Except Cold Storage, that one is free!!!!)
avatar: legend of angg the burning earth. seriously it takes about two minutes for 1000 gamerpoints :)
of course not. Halo 2 was made for the ORIGINAL XBOX system. therefore, they didn't implement achievements. there are NO achievements for original xbox games. you cannot get gamerpoints for playin original xbox games. although halo2 is fun anyways.
well, if 2100 Microsoft points costs about £20 then 800 would cost around £8.
