How can I get my games saves off my Xbox and onto my new 360? Will my memory card work in the 360 controller? What do I do about my Xbox Live subscription? Can I transfer it or do I cancel it and get a new one?

well, idk if the game saves can transfer or not, but the xbl sub will just transfer. you do not have to cancel. you will have to enter ur info into the 360, but thats it.

live will transfer. i dont think there is really a way to get game saves off of xbox, i think the memory card are different (naturally)

If I link them through my router, can I get the info that way?

That says it'd work for 360'*. Doesn't mention an original Xbox.

It looks like you may be SOL getting your old gamesaves over the the 360 unless you want to get adventurous...
