I have a COD MW3 (no, I don't play that game). It is really up to you. If you like all the extra MW3 (it is a $6.5K option!) comes with, why not. For many of those mod, you can get the parts.
I got my with manual, 403N, towing, automatic climate, block heater, hard top (body color), .... for ~ $39.3K. I bought this the same day I saw it!
No one can decide for you, it is a great jeep whether it has MW3 or not.
