I will do more running around with my next character to build hrs. but too me beating the game in as few hrs. as possible was my goal.
If I remember correctly, time passes accordingly when you fast travel as it would if you′re traveling normally so that′s not an issue. You do miss out on a lot of fun though and I don′t mean just battles. The scenery is among the many reasons my character never fast travel, as that can be considered teleportation and thus is not RP breaking.
