I wish more games would do real movement within your 2x2m sq space (I appreciate that not everyone has this space though). I remember being blown away by a demo of God for Tea, which actually uses available space so you can actually walk around for real. Though this only does it with 2x2m sq, it does an incredible job with this limited space (once I fixed a problem with Meta/App? that kept changing my border to stationary). I really fell for the illusion that I was using my own real-world steps to traverse the temple. Also, when you see all the mini-train tracks you get the promise of rides all around the temple, which definitely does not disappoint. It only takes 2-3 hours to complete, but I thought it was well worth it for the experience.
