An essential accessibility feature of any game is turning the brightness/contrast up beyond a point considered "the maximum the median player will want".
The fact that Minecraft removed that option pisses me off to no end. I shouldn't have to install a mod just to go caving while the sun shines into my room. Why put a limit on the brightness setting when not doing so costs 0 money?
If you think everyone can see equally well in low light you have clearly never gone stargazing with someone else.
