Believe me gamesas, 'everyone' who has played the original trio LOVES the game-play .. f*** World of Warcraft, and all the mindless .. childish WoW wannabes ... the quests in the original fallout games rocked!
Fallout 3 is great, but I never felt the same degree of immersion inside that engine, as I did with the original isometric trio! At the very least make it optional, as with Neverwinter Nights!
