I was addicted to Counter-Strike until I played DOD. After DOD, I lost interest in CS. Why wait out the round when you're killed when you can respawn much faster? There's no financial issues so both teams are more evenly matched. Most of all, this game takes place during WWII and which guy isn't a fan of WWII games and movies? As if that isn't enough, who can resist yelling out commands in German?
At first the game was very choppy. The graphics were pretty bad but excused because it was a newly developed mod with newer versions coming out every so often, until you have what it is now. The landscape was blocky and the vegetation can be laughed at, but there are innovations such as the stamina meter with the turtle icon. No longer can you run and jump around your enemy while shooting as you can in CS. There is a greater sense of teamwork, on such a level that CS can never match it. The only problem is that unless you have great chemistry with your teammates, the game will rarely feel like a team effort since everyone is off doing their own things and getting killed as a result. The new DOD (not Source) has a better score system that ranks players on team objectives captured rather than how many kills. This gets rid of the "me" in team. The game is easy to learn but takes time and practice to master. The current version allows the player to play as the British with their arsenal, a welcome addition to the game. Some of the game's maps can be argued to be favoring one side over the other.
I still play DOD, the non-Source version, because to me it is truly a modern classic. Sure, there are shortcomings that later games fixed, but remember that this mod was among the first of its kind. In my mind it has launched the craze of WWII games that followed due to its success. CS was the first online game that I adored, DOD is just as good if not better.

If you aren't able to handle playing as the Axis powers during WWII then don't bother with this. I remember several people disapproved of the game since I was playing as the Germans on the original Omaha map (now Charlie), cutting down the Americans while they were still in their Higgins boats. People have to understand that this is a game and what that means.
