The Meaning of Life, the Universe, and Everything.
a cool idea for Minecraft would be so there are four different seasons, summer, fall, winter, and spring. The seasons would switch in order every once in a while. In summer, there is less chance that it rains, and it can not snow in most biomes. There would also be a higher chance of sunny days. In fall, leaves change colors and sometimes fall off. There is also a higher chance of a cloudy day. In winter, there is a significantly higher chance of snow, and less animals would spawn. Also, you would not see animals that hibernate during winter. And, crops would grow slower. In spring, there is a higher chance of it raining. You will also start to see hibernating animals spawn more. Also, with all the months, a cool item would be a calendar which would tell you what season it is.
I challenge you to click on each link and read them all. Then, tell me how your idea is different and why I should support it when I chose to not support all the others. Why do you believe seasons should be added to the game?
As for adding it to the base game itself, it would definitely cause some issues, which is why mods are a thing. Orrrrrr perhaps a texture pack, cause how I felt is I really more felt the need of a change of scenery rather than the technical part of seasons. I didnt care for slower crop growing in winter or more rain in spring. The feeling of seeing the pretty fall colors was more important, the atmospheric feelings grabs your attention more imo. As winter approaches you get excited for the beautiful dusty snow falling on christmas day, buuuut then you walk outside and its cold, after a while the beauty dilutes and you look forward to the blossoming spring colors and warmth.... Then you want to go to the beach and get a tan amirite? But then theres no stopping the time when school season comes around and you get stuck in the sweater and longsleeves season, but all the school gloom gets washed away by the pretty red colors and orange and brown... then around and around and around it goes. So if you feel that you want more of the scenery, try looking for some texture pack
Or try and find a mod that supports full season technicalities.
