Beyond Earth Mods
I recommend trying the Colorful Tech Web mod. It helps identify things on the tech tree at a quick glance, much more easily than the subtle variation of icon borders between different types of items.
I recommend avoiding the temptation to install an “unlimited experience” mod. It sounds cool, but when 200xp units fight enemies with only 1 promotion, it makes the game super easy, which I find boring. I like a challenge. The experience cap keeps things on a more even playing field.
There’s also a “Beyond Balance” mod that looks promising. The goal is to make the game more fun and balanced like we did with Civ V: Communitas, while staying close to the core vanilla game. It’s a community-driven mod with a strong focus on responding to feedback, so if you don’t like a change, talk about it.
