Great game. Hold out for a patch or two before playing though. Game runs and is super fun but just needs a small tweak and a few bugs fixed to have an experience closer to what the Devs imagined. I'm looking forward to its future balance patches.
It improves on Civ in so many areas, but it also suffers Civ games usually at initial release - bit buggy, imbalanced and some features a tough light in options and mechanics. Battles are super fun, diplomacy easy to use, and city management is very nice. Strategic options galore.
