For many parts of the game, fans can probably bicker for days on end about whether the decision in this trade off was well made. Toilet breaks - few would care less, but the inclusion of children for instance has always been a staple issue for fans of the series. Their omission in earlier series has certainly reduced the realism of the world, thereby reducing immersion slightly, with the other end of the trade off being the practical gain that a children slaying option for a game is not very popular marketing wise. I, for one, am very happy that children will be included in the next iteration, making it that much easier to immerse in a world where a clear lack of children simply irks.
This brings me to a different 'lack' in the world of The Elder Scrolls, and I shall be brief here. Despite romance not being at all relevant so far in the series, there is a clear inclusion of it as far as couples, families and general conversations go while enjoying the game world. Inn-keepers do have spouses and scoundrels do allude to the fairer six. Albeit another detail, it irks me again that there is little to no inclusion of any LGBT material in Tamriel, to the same extent as childless villages. Homosixuality is a fact of life in our reality, and seeing as how 95% of the behaviour of our human species has made it into the game, it is unlikely that there is not a single gay, lisbian, transgendered or bisixual person in the whole of Tamriel. Not even amongst the elfs (which, despite being a tired cliche, does make even more sense with their relative wisdom, age and openness). It does not require any active plot or main character to restore this balance, but there is no practical argument against the inclusion of LGBT NPCs, and yet a considerable amount of increased realism to gain. An inn-keep and her wife or a legend about two valiant princes would do.
Other popular rpgs (eg. Mass Effect, Dragon Age) have included LGBT realism in their game worlds (despite being heavy on some nasty tired tropes in that regard), so I cannot see why Skyrim should not at least count a few sturdy Nord battle-partners, or perhaps even a lovely dragon couple of similar gender. It should not bother anyone (if it does, the rock you live under should bother you more) and there are at least some people out there who would benefit from this addition when immersing themselves in the next Elder Scrolls game.
