So far, my biggest issue with VR has been one of space, in that it feels like I don't have enough. Length is fine, in that I have 9 feet, which feels like plenty. In width, however, I only have 6ft. This means that if I'm standing in the middle, I can take one big step to the left or right and that's it. It feels like it holds me back, since I'm somewhat nervous about moving my arms around in some spaces, and therefore, I don't really move around that much.
I could move a bookshelf downstairs and get an extra 16 inches, but I don't really know if that'll be worth the hassle. I can't play the Star Wars experience (which isn't a big deal, but still kind of irritating), or this one RPG, since my space is below the requirements. One big thing I noticed is when I recently rewatched Giantbomb playing Rec Room and Jeff was able to walk around the entire inside of the room in the middle there and that would take me two teleports to do. If I could walk that much, it'd be awesome.
Still, I am really enjoying everything else about this, and it is really cool.
