So some people want the old maps back some don't. In some sense I do but I don't. I don't want to pay 15$ to get maps I could pay if I put my BO 1 disc in but I do want to play the maps with the Black Ops 2 features (guns,theatre mode,old characters).
What I think they should do is basically if you've bought all the DLC for Black Ops 1 you should be given these maps for free as a seperate download like if you want Kino you can download Kino only if you want Moon,Ascension,COTD,Five you can download those maps seperartly. This has been done for other games where you instert a original disc and it reads it like in Dragon Ball Z Budokai Tenkaichi 2 or in Battlefield 3 where you had to put in the single player disc.
