After playing all of them in the past few years, I realized that I nevere played the original CoD and CoD2 ( started with CoD3 on the Wii ).
So I went back and downloaded the first 2 games for the PC.
I wasn't expecting much, but the first game was definitely better then I expected, with dated graphics yes, but very playable and with great set pieces.
However CoD2....now that game must be my favorite ! With graphics not that much far behind newer entries ( granted it runs buttery smooth at 1080p on my 2012 PC ) and great gameplay, with a finite amount of enemies and less annoying deaths by grenades, it was just a blast to play from start to finish in SP mode, which was actually longer then other SP campaigns in later games.
Just a solid shooter all around, I'm planning of playing it trough again some time.
By the way, what's up with this poll starting with CoD 4, but skipping WaW and excluding previous installments of the series ?
Looks like a flawed poll....You should add more options
