Rise of the Tomb Raider's first shot pans over the vast, foreboding landscape we'll soon come to know. In many ways, it functions as a promise on the part of Crystal Dynamics: there are big things ahead of us. And at the end of Lara's journey, after we've seen her through this adventure, and experienced everything the world has to offer, it's clear that promise was kept.
Rising Tide brings other content to Beyond Earth as well, from new factions to new planet types. But these additions pale in comparison to the systemic changes Firaxis has made. There are bothersome issues with the new diplomacy approach, and some of these mechanics are too obfuscated to call excellent. But Rising Tide encourages new ways of thinking, and lends character to a very impersonal subject. That old Civilization mantra still echoes, just like it used to: One more turn.
