I think there was a Bitcoin Go type game a while back (geo caching bitcoin) but it never really took off. the reason?
people really do not care about the technology, they just want it to work and be easy and hassle free.
i think Steem takes it in the right direction. Definitely hassle free.
look at the video demo for this "your network" using btc for micro tx... it looks like some weird contraption built by some geek thats never socialized with another person and probably doesn't understand why no regular person is going to spend 5 minutes transferring 0.01 btc so he can upvote 1 article... :S
hahaha I just watched that video a few hours ago and was like wtf? I do think the TMZ thing is possible though. If someone does happen to start some thing like this I want on the team.
The game I envision would look more like this. Maybe with a virtual reality headset or some thing. Besides Bitcoin I don't know much about tech or games. Just make it happen.
