[Ambitious One]

It depends since Multiplayer isn't a factor then I'd go with whatever would have more value to it.

I have both Call of Duty 2/3 and have beaten them on Vet, pretty easy I must say. However, I kinda enjoyed the Call of Duty 3 storyline more then 2's because it was more like a story. I don't really know how to put this in words, but the graphics look better for 3 and the missions were more entertaining.

Umm, it took me a lot longer to beat Call of Duty 2 on Vet then it did for Call of Duty 3, I beat call of Duty 3 on vet 2 days when I started the first mission on vet while for Call of Duty 2, I took a 3 month break because I didnt feel like playing D-Day because I was scared, even though it was pretty easy when I did play it.

But with Call of Duty 2, you get the intense missions of the american campaign (normandy invasion), hill 400 and Africa involvement. With Call of DUty 3 you get the france perspective..yada yada yada.

Just get both, honestly.
