"XCOM: Enemy Unknown brings the XCOM series to a new generation of gamers who might be unfamiliar with turn-based strategy, and it is probably the best modern introduction to the genre, yet for those of us who played the original game to death it is a breath of fresh air – a brand new game that retains the heart of the series while bringing it up to date and streamlining it in good ways."

Amazon Prime subscribers can claim free PC games to keep via its Luna service.

XCOM: Enemy Unknown rebooted the series back in 2012, and has since inspired numerous new strategy game series to be born.
If someone gets into this I'd recommend getting the enemy within version. It's got all the dlc included so it's the better version. Wish the author would've atleast mentioned it. I didn't see it.
Fantastic game though. Xcom 2 is top notch also. I've spent countless hours in these games.

There are few things more gratifying in gaming than skillfully turning the tide of a conflict. And few genres provide as many opportunities to abruptly reverse the odds via skill and forethought as tactical strategy. To be sure, we are more often than not talking about turn-based tactical mobile games, specifically titles in line with the iconic landmark series (XCOM and Jagged Alliance) that made the genre a genre.
