I'm sure Someone else has posted the idea to hatch eggs and have certain traits of the dinos passed down.
my ideas on this (Someone knowledgeable in modding please take the idea)
1. A random factor on colors, but leans towards the parents.
2. Inherited stats/lvl Leveled stats have a trickle down effect 3% of the average of both parents (The number might be lower, but it needs to be able to just slightly push the little guy above the stronger of the two, unless the weaker of the two parents is extremely weaker)
3. baby dinos/egg hatching timers: Egg Timers should have a decent wait time. (at least a day) The mini versions of the big dinos (close enough) weaker stats, starts at level 1. The baby has 25 level to go through where it gets 4% of the inherited stats per level. (you kind of picked the stat points when you leveled up the parents.) Once reaching level 25 their model along with the level Grow.(to match how many stats have gone into he/she)
4. Dino nests: Creates a mother/egg link. You have to be down a dino to hatch one/six. (my spino constantly lays eggs, like 6 in 2 hours, isn't even mate boosted, like I dont know if the T-Rex is helping her out with that, but woah, pumping them out like no ones business.)
5. Picking up the egg and enabling follow on the mother starts the link?
