So even if the player administers the best available treatment, one or more party members will probably succumb to one of these diseases before the journey is through. Similarly, a player can choose the proper action in crossing a river only to have a capricious eddy capsize the wagon and drown one or more of the party members. It happened to the real pioneers and it can happen to the player. Similarly, if the party runs out of meat, the player will have to go hunting. Although their is no blood or gore in these sequences, it's realistic enough.
Deer fall over dead when shot and geese drop from the sky.
Again, I find it refreshing that OTII's designers chose to neither dwell upon nor sugarcoat this part of the story as well. If you make it through to the Willamette Valley or one of the other available destinations, you'll get to file your land claim and learn about what happened to your party and its descendants. In any case, OTII provides the player with a real sense of accomplishment after completing the journey. And not only will youngsters feel entertained by OTII , they will inevitably learn something new each time they play the game. That's quite an achievement for any computer game.
