I know this is a really old thread, but I feel the need to point out that everyone is ignoring the fact that almost every single animal in real life essentially has dark vision. Most animals can see in much less light than human can, so it's honestly not that surprising that so many races have darkvision. Also, as for orcs and goblins..... they live in the underdark, they kind of need dark vision.If you were to take a "realistic" approach to DND (yeah, I know...), in a world where darkvision is the norm, races without darkvision would be at a significant disadvantage from an evolutionary standpoint.
Heck, they'd probably have never survived at all.
There are lots of species IRL that can see better than people in dim light... which ones see in complete darkness? (5e Darkvision gives both, right?)I know this is a really old thread, but I feel the need to point out that everyone is ignoring the fact that almost every single animal in real life essentially has dark vision.

This is my only beef with Darkvision. Mechanically it’s fine if you actually apply disadvantage on perception checks to see (and therefore -5 on passive perception), but it bothers me from a verisimilitude perspective that it allows you to see anything in total darkness.There are lots of species IRL that can see better than people in dim light... which ones see in complete darkness?

This isn't particularly in response to your post, but your post added to some others in this and other threads and makes me want to write something about the old Shadow radio show (invisible by mental powers) and how invisibility (or hiding in the dark) work in D&D. I just can't get my brain to formulate it well at the moment.And even if I did have a party of all darkvision PCs... for my money the trope of "bunch of monsters hiding in the darkness attacking the characters that can't see them" is so overdone that I don't care that it'd be harder to pull off if the entire party had darkvision. I mean after all... if a bunch of creatures can hide in the bushes and trees outside during the day and ambush the party even though the PCs have completely normal vision in sunlight... running that same encounter underground with the PCs having darkvision is not that much different.
