Seasons such as Autum, spring, summer and winter
The idea is to to play survival mode or creative mode and choose a season you'd like to experience. They won't be roating seasons, you'd have to pick one and live with it for the rest of the gameplay for that scenario. Autum brings out the magic in every game, rustic colors, leaves on the ground are very magical. Spring and summer will differ on how much green there is in your current biome and winter will simply make all biomes white as they can be.
