ITS OPTIONAL
You cant complain that it ruins the game for you if you have the reasonable option to avoid it. You dont get penalized for not using it, if you want to enjoy the scenery and explore, the do it, no need to complain. I dont mind fast travel, I like getting alot done in little time, especially on 2nd playthroughs when I want to get to specific parts of the game. I just dont understand what the complaining is about.
