I've got a couple mod ideas that I want to start working on both of them will take a large time and effort investment to finish and I would like them to have the best chance of getting played, so which version of minecraft should I make them for. One of them is a form of transportation, but I mostly want to make it because of the underlying concept. That concept is multidimensional existence. This would offer a way to swap dimensional axis to as a way of getting around things. This is a pretty good example of what I am talking about. I might also add a way to walk between dimensions such as the end or the nether or any other dimension. This idea is a lot larger and is currently my end goal for modding. The concept is based on the lightbringer series if you have read that. I have a mostly full explanation here, but the short version is kind of like a magic version of tinkers that is based around light magic.
