ID put all their effort into graphics and absolutly nothing in gameplay.
Where have you been for the last 8 years, Just kidding;)
Other then the original doom and quake 1, ID has never really been known for creating innovative/creative gameplay. Doom 3 as I\'m sure most people expected is nothing more then a game that showcases the ID engine.
ID makes the best engines in the pc industry, as many of us have been saying ID ought to just focus on making engines and leave the game creation up to the talted gameplay developers. Matter of fact, most of the doom 3 engine was finished almost 2 years ago.
