I haven't played video games since Street Fighter II, and can't make a better informed argument, but if the scores are public for some huge games, I think it would be fun to bet on them (even if for "virtual currency".) Say, offer the games in "baskets", ranging from Farmville to MindCraft to WW. Bet on today's top score, biggest losers, etc. I say basket because individual score picks might be gamed.
Something like this might encourage more economic and financial research into video games, helping make the dismal science more attractive to "kids".
If it was accurate, we'd never hear about it. It'd be top secret.
They made $2 billion last year, I think.
George Ure says some weird things, but I find the discussions and predictions there fascinating.
All I can say is, I don't know what's going on.
