B/X Known World
Well, that's gamers for you. If you let them they will optimize the fun out of any game. If grinding rats would get them to level 20 efficiently, they would do so. Again, it depends on what your priorities are. Simulating a living world (that, by definition, includes boring outcomes) or emulating a story (that, by definition, precludes boring outcomes).It doesn't feel like either an interesting use of the world or a good story to me to have Superman spend lots and lots of time going after low powered villains who have no defense against his super speed, super brain, or super vision. It does feel like a good panel or two to have happen now and then though (usually while something else is happening in the thought balloons or conversation with someone else). Similarly for James Bond going after small time hoods.
