Everyone thinks the dealer cheats! Unless he has somehow gone rogue within the machine, he does not! He just makes good decisions on what die to roll next based on the outcome of his first roll. But I am also often surprised at how often he manages to get within 0-2 points of the line. If you would like to run a statistical test to figure out if the naga really does cheat with p < 0.05, please let me know so I can be aware if I have accidentally created a malevolent computer intelligence.
Thanks for the review, and you're totally right about the INT being too high. Honestly, 15 just seemed like a nice round number. If the stats really worked like in DnD, I am pretty sure going to 0 INT would make you essentially into a vegetable, instead of just a puppy dog.
