How so?
As far as I'm concerned, the day/night cycle is a feature that definitely adds to the gaming experience. Whether or not what it adds is necessarily a good thing for I&A, I'm not so sure, as although it can be awesome to fight in a new visual environment when everyone is paying attention, it can also be a pain as it is more difficult to discern friend from foe. I&A is a public server, and the simple fact is that for new players, daytime is an easier visual environment to learn and have fun in.
Like many vets, I enjoy the night sky from time to time, it's just a harder sell for I&A.
