Law of averages account for some unlikely streaks. I find Cautious to be no more lucky than myself overall. The more I play Realist the more it's balancing out. Rigged? Definitely no.
It should be noted that I haven't played enough games vs Realist to rule out coinidence entirely. And even if the odds are longer, the game is great. :)
Fun game. While I wouldn't call it 'rigged' at all, it certainly seems the higher difficulties increase the computer's chances at good rolls. It's not simply a matter of tactics I don't believe. Compare your first rolls with Realists and you'll see a constistant edge to the comp.
Great game. I just wish there was a difficulty like standard but with no item loss. I hate losing the items, but playing on easy is no fun/ challenge at all.
