How is making your own scenario significant house ruling? It is even encouraged in the rulebook?
Even adjusting the scenario can't rule out the possibility of a game where one person is left bereft of resources while another person has more than they know what to do with. I've been on the positive end of a game like that and didn't remotely enjoy it. It might not be a common experience, but the mere possibility suggest the game needs work.
Dice driven games like Alien Frontiers, Castles of Burgundy, or the recent Dice City (which is similar and I think superior to MK) provide the fun of dice without the agony of watching roll after roll hand the game to one particular player.
