Kingdom Come: Deliverance is the most realistic and accurate game I've ever played in any genre.
Warhorse studio's first game leaned heavily on real historians and details to make its story as accurate as possible, which is taking place during a war in Bohemia in 1403 and gameplay as close to realism as possible.
The main character Henry Of Skalitz is just an ordinary young man who only knows how to live like a young rebellious teenager, make chores and help his blacksmith father on the workshop, while listening his wise words about how to become an honest, wise and above all a good man in this medieval land. This all takes a drastic turn when army of Cuman mercenaries raids the mining village of Skalitz, where Henry and his family as friends are living. Escaping barely and losing almost everything and everyone he knows, Henry needs to start living by his own and learning the ways of a soldier. Learn how to using his brains or muscles or rather both to survive in this ruthless world and ultimately get his revenge. His growth from peasant to soldier throughout the game is carried out greatly and is joy to follow.
From the start the player will notice that this isn't an ordinary FP or RPG game. Gameplay feels challenging and it takes couple of hours, and deaths, to get a hang of it and in time learn the skills of swordsmanship, archery, fist-fighting, riding, reading. Yes. In 1400's was very common that children's of low ranking families couldn't read. Persuade people for your advantage and keeping your appearance, gear and weapons clean as well as sharp. Also there is familiar hunting, mixing herbs, collecting resources, searching treasures and helping people in need who you pump into your travels.
I wouldn't start browsing the whole map through at once, what I normally tend to do in open world games, but take my time in area after area where the story takes us by doing main and side quests because this game is challenging at first. You need to develop Henry's skills with time before charging in highly guarded castles and trying to pick a very hard lock with your low lockpicking skills or stealth abilities.
Talking about side quests. The effort what Warhorse has put in them, reminds me on The Witcher 3. They aren't normal, easily forgettable side quests where you need to pick some meaningless item or kills some mean neighbor who owns someone money for some NPC who's name is different but modeling same like the last dozen people which you've already seen. Side quests are interesting stories to see and usually challenging mission to accomplish. Some of them have effects later in the game and some of them launches new missions. Many times I needed to save before starting them, because many times I either stepped on a branch or someone just happened to walk by on his patrol causing the alarm and me reloading my previous save for completing the mission perfectly. Because I choose to be stealthier and wiser on my playthrough instead of merciless, short tempered killer.
Story is very interesting and it takes its time, but many times it stays hanging on the background because the world itself is so huge and full of interesting activities. Interesting people to meet and important relationships to create as connections to form so you could continue your guests more easily. Or taking a break from all the world's stressing obligations and go hunting at first very challenging bow mechanism but in the end, very addictive.
You will encounter one particular very well developed relationship between your main character and another high-ranked individual which is, on my opinion, one of the best formed relationships in gaming history.
Finally, Jan Valta's chilling and emotional score ties all of this epicness together.
Although this game is amazingly detailed and feels great, it has its flaws. Unfortunately. Loading times are frustratingly long and there are still bugs and glitches than back in its release which caused frustrations among players as well as few low scores from critics. Luckily patches have fixed majority of them so the gaming experience won't suffer almost at all.
