This is a really good idea.
It's like horse racing, only with gaming.
The thing is there are tons of things you need to consider. It would be too easy for gamers to throw games and get their friends to bet on the other guy to make big money through cheating. This is just one obstacle. A project like this has a million different things to think about before doing it.
I totally agree with you. Thank you for the response. Indeed, fairness is a big obstacle. I was thinking about using the statistics to prevent that. For example: If one player has a lower than normal statistic throughout the game, the game is cancelled.
What things do you think are worth looking into?
