they added over 1.7 GB of stuff, so why is the "plain" version on xbox originals and not the lost chapters?

heres my post that lists everything they added to this game:

check it out, lots of cool stuff was added......

its more than worth it to pick up the lost chapters on disc, it sells for $10-17 its worth every penny.

To save hard drive space?

so is this lost chapters or no i want to know b4 i buy this can u tell me plz

the game on live is NOT the lost chapters, just the old "plain" version.
you have to find the actual disc game to get the lost chapters version, it is backwards compatible.
it is usually only $10 if you can find it.....it is very much worth it.
