So I'm fresh off my first extremely embarrassing loss in Endless Space and I need a little guidance so I don't repeat the showing. I mainly researched the exploration and expansion tree and I found myself horribly under-equipped weapons-wise. So after watching ship after ship get shredded under the guns of the enemy, I figured I needed to spend some time on the military tree. That didn't work in time. Which was bad.
SO... how much do I need to divide up my researches to maintain a viable balance? I also noticed that I go some military hardware on the tree I was traveling down, mainly increased ship sizes, but I hadn't grabbed them as I went past. Are those the things meant to keep the tech tree viable?
