I'm sure this has been discussed here before, but the dynamic that makes the game more interesting is not pure EV, but how the value of money changes relative to how much you have. For example, you could say that taking $150K is equal in EV to a choice that will yield either $0 or $300K half the time each, but most people would take the $150K, because the second $150K has less value to you than the first one. That said, would you take $100K or take option B when it will be either $0 or $300K? Somewhere in there is a line for you where you take the risk. It's not really just an EV thing unless you already have a lot of money. I think this is why the game is interesting.
