About cycles, my thought is that it has to be slightly compressed, ratio about 1:2. Leaving to be 1:1 brings issues: if i use to play videogames at night, i would always play darkness and vice-versa. Furthermore, i would make cycles someway async with real time world, to avoid that, for example, at 16pm is always dark. Basically, i think that we should NOT know where the cycle would be before logging in. This is quite impossible, so at least try and make it harder to guess I voted 1st option on gamma: pure darkness, no gamma correction. Enjoy the dark or play cod ;)
