I know there's been a million threads like this before, but here it goes.
Should I buy COD WAW from the Xbox live games on demand? It costs a few dollars more, but there are pros such as:
You can not lose the disc
The disc can't get scratched
It is on your hard drive forever
There are cons too:
Can't sell
Can't transfer to a different hard drive if I get a new one
Tell me yes or no and explain your reasoning.
