[quote name='dastly75']Well historically Bungie hasn't released any forged maps for $$ and if you read all the in depth interviews about their DLC maps on their website, they put a lot of thought into them, even if they're remakes. Furthermore their past remakes have been from last generation stuff so they had to update their assets and usually they have an all new skybox as well as tweaks to the map so that it plays well in their new game.
The thing that annoyed me about the CODMW2 maps is that they're straight ports of old maps that I still have on my COD4 disc. Despite my waning interest in MW2, I probably would have bit on those map packs if they were 5 all new maps rather than just 3.[/QUOTE]
While they were ports, yes, Overgrown and Crash received graphical updates with the MW2 engine. If you go back to COD4 they don't look as good as they do in MW2. There's also the new gametypes, guns, etc of MW2 to play on the maps. Vacant and Strike, however, were changed along the lines of the Bungie remakes. Map geometry was altered to balance gameplay and both were updated graphically as well. Both maps take place at sunset now which kind of goes along with the whole skybox thing.
I really don't get the hate on the MW2 maps being $15. It's still 5 maps that you get to play in MW2. It's actually a better deal than Halo or Gears (Combustible) maps were at $10/pack.
