In todays terms, games are more and more becoming 'interactive movies' with large cutscenes and non-interactive envoirements which are only there to improve admosphere. Unreal Tournament 2004 still looks nice even for todays standards, but the best thing that you can expect from it is the gameplay. You'll never find anything faster than this (minus the sequel UT3 of course), you walk fast, your agility is immense, your arsenal will rarely run out of ammo, and there is a possibility to make 5 or more kills in a row. You won't walk through this as slow as in most newer FPS games, there's always something to do!
