TLDR: Get the SWvsST mod and follow the instructions below - this is the best 4X ever! ---------------- original review --------------- I've played Galactic Civilizations II (at least 100 hrs) and Galactic Civilizations III (20 hours), and I like GC2 the best, and that's because I feel like I've come up with a strategy that uses the technology tree a certain way. As an aside: I might have even played GalCiv 1 - I'm not sure though. I do remember being really disappointed when GC2 first came out that it was missing "death stars", so I think i got the impression that it should have those because I must have played GC1 first. Later GC2 came out with the "Ultimate Edition" and that did have death stars, and at that point I understood that StarDock loves to milk the player base with DLCs, which they continue to do to this day. Hey we all have to eat right? When I tried GC3, it didn't hook me because I could see the technology tree had been changed a LOT from what I was used to. I still tried to like it and play it, but it never hooked me and it felt like they had just made everything more even. I couldn't find a huge advantage in the tech tree and my playstyle anymore. Mind you…

Excellent strategy game. Replay value is very high as there are tons of things you can tweak and alter to change up the difficulty or length of the game.
