Mesozoic Dawn Grow up, lay eggs, try again

Every life starts small and fragile. As a juvenile dinosaur you forage, stalk prey and avoid anything bigger than you, which at first is nearly everything. The core loop is Growth + Nesting = Evolution: eat highly nutritious food, reproduce, and your species breaks through to a stronger tier. No XP bars, no grinding levels. You eat well, you nest, you evolve. The payoff is watching a bloodline climb the food chain over generations.

Survival here goes deeper than a hunger bar. Stomach, lungs and heart are linked: hunger, thirst, stress or injury directly damage organs and lower how efficiently your body converts food into growth. Temperature, humidity, oxygen and energy form a web where every decision matters. The world is split into climate zones, and each species has its own temperature and humidity needs. Finding the right zone does not just keep you alive, it speeds up your growth. Weather turns dynamic too, with dust storms and floods rolling through. Pick your habitat well and you thrive; pick badly and the environment kills you before any predator does.

Death is not a full stop here, it is a generation. Gather stone and wood to build a nest, your safe haven and respawn point, then choose asexual reproduction or find a mate. Environmental temperature even decides the gender of your offspring, and males come with natural advantages in size, attack and defense. Manually brooding your eggs doubles hatching speed and builds up generational bonuses. Offspring inherit their parents' good genes, with random fluctuations pushing attributes past their limits. Over successive generations you can forge a peak lineage that no single life could produce.

This is open-world survival crafting with a prehistoric twist: instead of chopping wood for a cabin, you gather stone and wood for a nest that anchors your whole lineage. Over 70 species roam sea, land and air in a colorful low poly style, each with its own survival instincts. AI herds wander with independent behavior, and in special seasons they gather for large-scale migrations, dozens of dinosaurs rushing past in the distance. That is both a huge threat and a huge opportunity. You can also tame a wild dinosaur of the same species into an AI companion, and your hatched eggs can become AI offspring that obey combat commands like Follow, Attack, Defend and Protect, giving you loyal territory guards.
