The Modern Warfare that started it all. I didn't grow up with the franchise at all so I don't really have any attachment or nostalgia to this game. I will say that I only played through the campaign and not the multiplayer because I've heard it's very dangerous to do so and Activision doesn't give enough of a shit to fix it. Overall, I thought the game was serviceable. I had some frustrating snags (granted I was playing on Hard mode, one step under Veteran) with the last couple of missions, which makes sense in terms of difficulty curve but I felt there were some deaths that weren't my fault. The story was pretty fun, I like the dynamic between the SAS unit specifically. General COD gameplay which I'm sure gets a bit more refined with the later entries.
