📋 About This Mod
Dinosaurs have more realistic average lifespan, life cycle goes faster and more generations are born over time.
In vanilla game dinosaurs live stupidly long. There is an achievement requires to breed 5th generation and it's almost impossible to see even the 2nd generation within a reasonable amount of time.
This MOD reduces the lifespan of all species to reasonable amount of years, so older generation dies faster to leave room for young adults. To compensate they breed more frequently in their lifetime but each breeding has less eggs. Juveniles also takes less time to mature.
The goal of this MOD isn't about to breed hundreds of dinosaurs within an hour, but trying to find a more sustainable way to keep the life cycle going.
This MOD has changed many aspects on dinosaur balancing, please remove other dinosaur related MODs since it's unlikely they are being compatible. With the exception of Better Ecosystem, which has no conflict and I think works well with each other.
Although not essential, for full experience it is strongly recommended to also get Better Ecosystem which solves some issues on dinosaur combats and predations. The screenshot shows the ecosystem gameplay after 1 hour of in-game time(less than half an hour in real world), and we already got 2nd generation of juveniles. In vanilla game it would take roughly 2-3 hours.
If reducing lifespan isn't your thing but you still think they breed a bit too fast, alternatively you may try Birth Control which puts a lower cap on each species' total population.
