I would really love if someone made a game where you could play an MMORPG while walking slowly on a treadmill. If you had combat against another character though, you would have to run on the treadmill and that would affect the damage you could do – whoever ran fastest would do the most damage. If you had a higher level character, you would do a higher level of damage as well. This way say a Level 10 character who could run 6 miles per hour would be equal to a Level 6 character who could run 9 miles per hour.
Pokemon Go is sort of like this -you wander around in the real world to collect Pokemon and level them up. It is highly addicting – Laurel and I played it for an hour or two last night walking around in the real world. Augmented reality is pretty incredible stuff!
