I was thinking more perhaps as a way of incorporating or even explaining certain gameplay features. For example, look at the idea of stimpaks. At the start of the game, I would imagine that stimpaks would heal a relatively low amount of health, and that as our level and stats increase, so will the benefits of taking a stimpak. It could be incorporated/explained during gameplay that this may be a side benefit of being in stasis for such a long time. If my theory of the PCs son being the main antagonist is correct, this idea could even be extended to explain some kind of regenerative ability that they would have, making them an even more challenging and dangerous adversary.
