The only games I've even encountered fast travel in have been Bethesda games. Given how much time Oblivion, Fallout 3 & NV and Skyrim consume playing the game with it; I can not imagine how much more time it would take without it.
One of my friends who had never played a game as massive as one of the Elder Scrolls games picked up Fallout 3 a few months after it came out...He got addicted to it and played it for a week before he figured out fast travel.
