It may pick a standard route if you don’t care, or you can click-and-drag along the particular route you want to take. Or try and prioritize sections.
Example 1: I want to hit Super Capital Chasis as fast as possible. So I just click on that bubble in the research tree. It will pick the fastest route possible, regardless of how many things needs to be research. The emphasis is on TIME.
Example 2: I want to hit Super Capital Chasis as fast as possible, but I want a particular something along the way. There could be a simple feature to click-and-drag along the path you want.
Example 3: Those who don’t want the automization of research can just click on one at a time and wait for it to complete.
Example 4: Super Capital Chasis. That’s priority. But I also need Gravity Wells! Simple left-click for Priority 1. Then select Gravity Well for Priority 2 with a right-click. It researches Priority 1 first. Once completed, it begins to work toward Priority 2. Both instances being capable of re-routing your research before you begin, or during ongoing progress.
This idea gives real credit to the phrase ‘Tech Tree’ in RTS games. It also allows you to SEE how much of the whole tree you have researched. It gives an idea of how far you have to go so people can gauge their status better rather than having to memorize the entire tech tree and know ‘how far’ something is away from where you are. AS things research, there could be a blue progress bar along the branches of the tree towards something so you can watch it go.
