In case anyone gets FOV induced motion sickness here is how to fix it by finding and opening your config files.
Find your Appdata folder
Open Local - 4A Games - Metro LL - the next folder within that - user
Scroll down until you find r_base_fov which is about halfway down
Change that to a number you prefer. I'm experimenting with 80-100 while finding an option that works best for me.
Now that this fix is in, I'll be looking at the game this week and work on my first impressions later in the week.
