They have too little entertainment value for a too small market, yes - not necessarily because they're not realistic enough, just that people don't get very excited watching a counter on screen go up. I realize one could say 'soccer goals are just a counter too', I dunno nor do I have the inclination to really formulate a theory on why I feel this won't work - let's come back to this post in 3 years and we'll see what the market thought about it. I'm not going to invest in Ultimate Samuraisword Championship, LLC, that much I know.

But hey I didn't buy BTC 3 years ago either so what do I know.
