Let's leave aside all the bugs with what is there beforehand. Now, nothing was really "poorly" done, just to an insufficient degree. For instance:

* Malnutrition should be long-term, and tie in with various food-types and diseases (e.g. gout)
* The sim should be less LMoE; there should be real options for cooperation with villages beyond basic trade, as well as some social stakes beyond a barebones "reputation" system, as cooperation in these environments was and is, after all, necessary to thrive if not to subsist
*Actually, this game might make the most sense as a village sim
* Predators (e.g. wolves, bears, lynxes) are too lethal when they hit, and players too unlikely
*Combat fatigue should be scaled down; it takes more than 5 minutes of tussle to become incapacitated by exhaustion
* Performance should be modelled with more finesse than just in terms of fatigue and injury; certainly, different sorts of injury should affect performance differently and not all as just some combined scalar penalty
* It should be possible to build weight and strength, instead of being stuck with it from character creation
* Why does everyone have to start as a 16-y/o?

etc.

But it's a charming little gem for a one-man project.

It is a useless waste of time


As opposed to - what, exactly?
