Sid Meier's Civilization III vs XCOM: Enemy Unknown
Sid Meier's Civilization III
Sid Meier's Civilization III is a compilation of the third iteration of the award-winning grand strategy game franchise, Civilization, as well as all its associated DLCs, namely the updated and enhanced multiplayer expansion in Civ 3: Play the World and new civilizations, scenarios, and features in Civ 3: Conquests. The game definitely improved on its predecessor by a mile, providing players with basically more ways to play. Due to this, the game has a depth that surpass the other games the franchise has produced.However, its multiplayer has been suspended but if you like, you can still play the game on LAN. Not to mention, many other aspects of the game, like the graphics and some of the features, are becoming rather dated as well. So, unless you plan on playing only single player or on LAN, you might want to grab a slightly newer version of the game if a deeper gameplay is what you crave.
XCOM: Enemy Unknown
XCOM: Enemy Unknown puts you in charge of a secret paramilitary organization known as XCOM and as its commander, you'll need to build a functional base, manage your resources, constantly improving your technology and give tactical orders to your team when taking on a global alien invasion. The game is, obviously, part of the award-winning turn-based strategy game franchise, XCOM, which is famous for its incredible action sequences, as well as squad management and turn-based combat systems. The game will also see you as a diplomat of sorts as you'll need to interact and negotiate with various governments during your missions.XCOM: Enemy Unknown is one of the best turn-based strategy game there is (and yes, this means until now). However, the game can be quite difficult especially for newcomers to get into, and to truly appreciate the details and the flawless gameplay mechanics, you might need to put in quite a bit of time into the game. But if you do all of that, you'll be richly rewarded with one of the best gaming experience you'll ever get.
