In the case of vanguard, you don't have the option to have the old, ungamified, version. (Can a game not be gamified?) In the case of walking around, you can still do it the same way you always have, if you prefer. What's the problem here?
A game can be fun; it can be deep and complex...or it can be like farmville. The problem is that companies are moving in droves towards Farmville type products because addiction is more profitable. I would like this community, as the vanguard of tech development, to see that there is a problem with this.
