So like many others I have yet to buy either DLC map pack. Mostly because I don't have the 40 bucks just laying around. Yet at the same time I don't think I'd buy them even if I had the money.
Both map packs include five maps, both having a COD4 remaster. With the 1600 microsoft point cost the maps are worth about five dollars each. That's right, five dollars for a single map and unlike packs from other games like Halo they will never become free. So even when Black Ops launches you'll have to pay for these.
Even with the somewhat ridiculous price a lot of people have purchased both of these packs. Now I can't blame people who make a living off of Call of Duty videos and those that compete in tournaments for buying these but as an average gamer I could never bring myself to purchase these.
