Beautiful graphics, a well-known story, and interesting roleplaying elements are brought down by overbearing difficulty.
The graphics aren't hard to render, but they're awesome nonetheless. On the grand scale, you see the beautiful landscapes of Britannia, the sparkling oceans, and the huge forests. When you zoom in, you notice the plains are detailed with swaying grass, the character models are detailed even to facial features, and the buildings are carefully modeled to look good from both angles. One of the more fun things to do in the game is just to simply watch two armies go at it - you witness a battle of epic proportions.
The story doesn't vary a whole lot from the well known tale of King Arthur, but it does take an interestingly dark view on it. The music fits the game well, and thus enhances it.
As the title "Role-Playing Wargame" states, King Arthur contains quests and decisions that affect your two alignment scales - between Christianity and the Old Faith (Druidism), and between Righteousness and Tyranny. Here the game introduces a pair of axises with those rankings on them, and throughout the "grid" are placed abilities and upgrades - so a person who is aligned with the Old Faith and is a tyrant will receive different upgrades than they were if they are a righteous leader, but not the same as a Christian tyrant. All in all, it's a very interesting role-playing concept that could give the game some high replayability except...
The game is tough. I am no RTS expert, but I've played my fair share and can't even beat it on the second-to-easiest difficulty.Your enemy is ruthless, and the battles require above-average skill to win without losing half of your army (which is saved across battles). What's worse, the battles are almost consistently the same, with very, very little variation. And while you can choose to auto-battle and skip an encounter if you don't feel like going through what you just did 10 minutes ago, this causes you too lose a large portion of your army to the enemy (assuming you even win).
To make matters worse, the interface is confusing and hard to understand. There's a thousand different buttons to click, and what time you don't spend in the lengthy, repetitive battles is wasted going through the interface to catch up on the story, or upgrade units (which is equally confusing), and the like.
All in all, the story, music, and visuals in this game are prime. The role-playing elements are certainly fun, and it has all the potential to be a great game except for confusing interface elements and somewhat overbearing difficulty. If you are an RTS lover and experienced player, then consider this game. But on the other hand, it's only fun for the first hour or so.
