His statements are actually very true, BGS designed the gameplay of OB only to be used with fast travel, there really was NO serious and realistic choice. (Let's be logical here, shall we?)
Besides, I remember in MW that there were LOTS of quests that you were free to aquire while walking down the road. In OB... well, it nearly (or possibly... never) never happend.
MW's system allowed just enough amount of fast-traveling around the world while still being restricted to the bounderies of "No, if you want to get from point A to point B fast enough a travel miles over miles of ground and mountains, you'll have to think a little as to how you will do it."
And the most interesting and I think, dare I say it, never mentioned point is that it kills the feeling of being trapped somewhere or being lost. Seriously, think about it, I remember when in MW I felt lost and trapped in Red Mountain, and in times I really got lost, but boy... when I found the place I was looking for... I was so [censored] happy and satisfied.
At times it was annoying, but it always, and I mean ALWAYS, added to the immersion and experience of the overwhole gameplay.
thanks
