Personally I hope that - the dinosaurs will have lifespans which revival their movie counter parts.
Remember that Rexy in Jurassic World & JW2:Fallen Kingdom is the very same T.rex from the original Jurassic Park. She estimated to be about 30 years old (as she was about 5 years old at the time of the original Jurassic Park took place).
So having a healthy, nearly 100% DNA, T. rex live up to 30 years(in game time) would be great, and add a sense of realism to the game. And it would also be accurate to movie canon. As the oldest T.rexes are estimated to have been in their late 20's to early 30's at the time they died.
