I need your opinion!

How many people do you think would be interested in an open-source, small-ish survival game with less focus on enemies and more focus on the environment. Effects such as sickness/colds, sunburns, not cooking food right and others would damage you instead of enemies being the major cause of damage. The health system would be through limbs, if your leg takes damage once you can't sprint, next you walk slower and lose stamina just by walking. If you hurt your arms you can't use axes/cut things up. Along with that the game would have mods, effecting the world, adding items/weapons, new mechanics or UI designs and elements.
