plot is unrealistic. No children and fat people? the hell?

Not sure if trolling, but it makes sense to leave the obese out of that journey. As for kids, there was only one. The emotional assault in ME3.

bs and how come there arent any thats awake?

100% of the npcs are thin/fit/young. that doesnt make any sense

there should at least be 1 child or 1 fat person in the game but nope. zilch. nada

what is up with bioware not adding fat ppl or children npcs?

Check the codex...they earmarked a section of the Cryo called "the Refrigerator" to used in case they run out of rations/supplies searching for a homeworld or the Nexus

It makes perfect sense... 600 years worth of cryostasis is probably hard on the body and people going into it obese probably don't have as good a chance at survival as people who are fit.  Ditto for the very old and the very young (who are still growing and developing).  The Initiative would have almost certainly had a selection process that would have favored those most likely to survive the cryo. 

The game also mentions that birth controls were put in place to ensure that no children were born until they had viable colonies to sustain them.  At that point, they would want reproduction to occur as quickly as possible and the birth controls would be stopped... so adults of breeding age and ability would likely be favored over those too young or too old.

Tokenism for the sake of tokenism (which is what you're suggesting by saying that there should be 1 fat person and 1 child) is what doesn't make sense.

So... that's why your avatar is some THIN sexy young chick, eh?  Put your money where your mouth is.

This can't end well.

In my opinion Bioware fails at creating realistic and immersive worlds/enviornments. They are good at creating stories and great at creating characters, but their world immersion is something that is really lacking especially when other AAA games like Assassin's Creed and Witcher 3 feature children. 

This is not relevant, but children in games annoy me. My general reaction is, "wtf is this kid doing here? I will likely have to kill someone soon." It's easier when they're not around, and no, it doesn't hurt my immersion at all.
