doom 3 is a graet game but it lacks the intensity and hardcore action that dominated all the previous id titles.
the mod community have created mods that play beter that doom3
the most important attribute of the game is simply the environment
you can not find a game that is able to create what doom3 has created without being considered silly
the excellence od execution and the way the environment is made and presented makes doom3 the game that it is
simply the best & the unbeatable sci-fiction shooter ever created and beleive me i have played them all
the mods give the game extended life and they are really really really excellent (in hell-classical doom-annihilation- hellisland)
this is why the game is great
