That one was a big surprise since it was my first Kojima game and I have to say, it did a big impression on me and kept me thinking about it for weeks after I had finished it. I agree, the walking/balancing is something you need to get used to, but after that it totally adds to the immersion. Also, there will be other means of transportation later on. They all come with their pros and cons. I envy you a little, this is a game where I’d like to wipe my memory and start all over again. Have a great time!
