XCOM
Shifting gears to Turn-based strategy: XCOM: Enemy Unknown ushered in a rebirth of the classic series. Notoriously difficult, XCOM has always been about making difficult and sometimes punishing choices, sending your team into harms way to take on extra terrestrial foes hungry to tear them apart. The experience of your troops matters a great deal. More experienced soldiers can get away with making daring and rewarding moves against the enemy that would typically leave some punk-rookie face down in a pool of blood.
Managing your resources and planning your every move isn’t enough. You can spend as long as you like deliberating your next turn but you’ll still have to watch it all unfold with bated breath, praying that your plans pan out. The devastation of a botched turn is heart breaking. Especially when it means the loss of a soldier you’ve been carefully fighting with since the first mission.
