MINECRAFT -- Survivalist mode

making it more realistic with ACTUAL condition building, imagine this: Mining increases strength, running increases speed and swimming increases breath capacity. a dehydration system to make it realistic, not spamming W to get faster, and they have to stop and recharge on actual nutritional food and water/milk.

fighting increases combat strength and durability.

and it's not forever, it's if you do these things regularly, actual mining, crafting, swimming, running, fighting.

meaning Minecraft will get easier for them if they work hard enough.
