If there's one thing I like in the trash that is Destiny PvP, it's that the maps have a day and night cycle.
I've wanted that in Halo for sooo long. Mixes things up a bit
Same. But I wanted it tied with slight weapon and vehicle changes. For example, I once saw a Valhalla concept with snow etc. And I thought, why not have night and day cycles.
I remember playing World at War by Treyarch and they had this map Makin which was set at night, and then they released a free daytime version. Completely changed the pace of the map, key spots were no longer easy to shoot or hide from etc.
So using Valhalla again, I thought why not tie different slayer settings to night and day cycles too. Imagine Valhalla in the morning, nice and bright, clouds, the skybox is clear with a few UNSC ships flying around. The weapons are primarily UNSC etc. And then there is a nighttime version that is elite slayer, the skybox shows the Covenant destroying the UNSC in the sky, and because it's elite slayer, everyone is elite and the weapons and vehicles are Covenant based. This was back in Halo 3 days. Just a way to visually change the map, and also change the gameplay slightly.
