Maybe you are looking for an excellent turn-based strategy game like X-Com.
Xcom, also called “UFO” by players, is the most classic strategy game. Players need strategies with extremely high-risk factors to fight against unknown enemies. There are 7 series in this game. If you are free on weekends, you can all try it out.
1. Mutant Year Zero: Road to Eden
Mutant Year Zero is a tactical strategy game that combines the classic XCOM gameplay style. The game's background is set in the post-human era, where mankind was completely extinct after the nuclear war.
After many years, mutant people and mutant creatures evolved. They must find food among the remains of civilization. To survive, you and your companions must personally venture to explore.
2. Warhammer 40,000 Mechanicus
Warhammer 40,000 Mechanicus is another strategy game that requires expanded thinking horizons from the player. As for the gameplay, you take control of one of the most advanced armies in the Imperium in terms of technological assets.
The main storyline follows the footsteps of Magos Dominus, who is tasked to rediscover the Necro planet of Silva Tenebris. In the game, you can freely customize your team; add, update, and delete resources; and discover new technologies on the way.
All in all, Warhammer 40,000 Mechanicus is a unique tactical game that takes on exhilarated combative skills and on-point decision-making.
Xenonauts is a strategy game, just like Xcom, in which you have to maneuver a multi-national military organization through a set of hurdles in the Cold War era. Now, what's queer is that you are not defending yourself from humans or armies from the neighboring countries but aliens.
Ring a bell, huh? For particulars, you are supposed to control and command small squadrons and exterminate extra-terrestrial entities from the face of Earth. Not to mention, the game also includes a Research tree for unlocking new projects. Xenonauts is worth a shot.
From my personal experience, Battletech is a phenomenal game that will keep you on your toes for countless days and nights. Why? The game is all about interstellar battles where you fight among different noble houses with mechanized robots (combat vehicles).
You can pilot these crafts and tweak (read: customize) them at your own will. The game is all about how you strategize against your enemies for reaching the right resolution. Last but not least, there are around 30 battle mechs you can choose from.
5. Phoenix Point
The surprising thing about Phoenix Point is that the creators of Xcom created it. So, keeping that in mind, you will be finding many similarities between the two titles. For example, the tactical battles are the same but more refined and nuanced.
Apart from this, it has the same strategic elements that Xcom brought with it. Not to mention, the narrative of Phoenix Point is quite riveting as it projects our world being overrun by some unknown alien species. Now, only the Phoenix project can blow a kiss of life into the last wisps of hope humanity has left in itself.
6. Invisible, Inc.
Invisible, Inc, just as the name suggests, is a completely different game where stealth is one of the game's core elements. You are tasked to infiltrate dangerous corporations and organizations while ensuring that your invisibility cloak is not unveiled. So yeah, it's a game where everything is stealthy and has to be done from behind the curtains.
You can use on-point precisions, tactical shots and collaborate with your friends together in high-profile areas. Not to mention, you can select from up to 10 different unlockable agents. And probably find yourself in a different generated random world on every launch.
7. Fire Emblem: Three Houses
Fire Emblem: Three Houses is a unique game when put against all the other titles on the list. Here, you are tasked to prepare the students from the three renowned houses for an upcoming war. The game is brimming with strategic analysis and battle skills that the students would acquire to get the upper hand over the enemies.
As their only professor, you have to be vigilant and conscious of the motives of the three houses participating in the academic training.
8. Battle Brothers
Battle Brothers is an immersive title if you know how to go about it. For particulars, it's a tactical RPG game that is set in a medieval fantasy world. In essence, you as a player get to decide where to go, what to buy, who to hire, and which contracts to opt for, for successful mercenary endeavors.
Not to mention, it's a strategy game where you devise surreal yet applausive plans on the battlefield. Moreover, the best thing about the title is that it has a perma-death feature which means whoever dies on the battleground remains undead unless re-incarnated for some reason.
9. PHANTOM DOCTRINE
If history has always enticed you, then the Phantom doctrine is a title that shouldn't be ignored at any cost. Why? Well, it's another strategy-based game set in the era of the Cold war. As espionage, you get to unveil the mysteries behind the cold war and the organizations that have been crusading against each other in the name of power dynamics.
Although you are supposed to prevent a global conspiracy from reducing the world to shambles, you also have to make sure that your character develops as a skilled spy to reach a definite resolution.
10. Valkyria Chronicles
Last but not least, Valkyria Chronicles is a groundbreaking entry that is set in a fictitious world. As for the timeline, it's somewhere around the 1930s where, currently, two superpowers rule the continent: Empire and Federation.
It's a game that fashionably projects political discourse and asks the player to think shrewdly when executing their plans for the missions. All in all, you get to use special powers from an ancient race and select from around 100 available customizable characters. What else does one need?
