Erm, I don't like to work alone...
First of all, it's boring...
Also, I can make. But I got little with Ideas. (Because I have used the most of them by now
)
Also, I don't think there would be many that would download/use it.
Because Mw2 is very soon out-dated for many. (Mw3.)
Also, I think people will focused on being able to mod Mw3. So I am sure many will try to make it able to mod Mw3.
Also, why would anyone but a lot of work into this when there is so much more you can do...
But after what I heard.
Some guys from Mw3. (GSC Coders.)
Created something like deathrun.
I don't know if they really made it or not...
But I know that it would be very good if they made it.
(I think they found out that it would take to long to create a new "side-game". So it might come as a "DLC" later...)
I can't say/tell that this is 100% true. But I read the mail, and it looked real
