I have played Fire and Sword for 9.5 hours and I will be going back to Warband. I compare Fire and Sword to comparable mod say, Teatrc's 'The Eagle and the Radiant Cross' mod for Warband, and with the exception of 'terrain texture quality', Teatrc's is far superior. I'll explain why:
Battle continuation: This is a huge flaw. In a game where firearms are the norm, having to feed your army to the auto-calculation monster every time some random brigand gets a lucky hit in, even if your force far outnumbers and out-classes theirs, is horrible. It also restricts the player's ability to 'watch' the battle as they only way to ensure victory is to stay out of the line of fire. Teatrc has battle continuation.
Diplomacy: I could be wrong about this, but so far the game does not seem to incorporate any of the elements of the basic 'diplomacy mod' which is staple of any version of Warband that wants to be taken seriously. Diplomatic interaction seems to be limited to war and peace. There are no Non-Aggression Pacts or Defensive Alliances. I guarantee that such political elements not only existed during this time, but were fundamental components of the era. Teatrc has Diplomacy.
(By now many of you are probably saying ‘go and play Teatrcs mod then’. I plan to, but my point is that a professionally designed mode that costs 15 bucks on steam should, I think, contain more than a free mod made by someone who is not professional. The identification of games that do not hold to this truth increases the integrity of the market).
The Campaign Map: The map is historically accurate with regards to most town placements (I compared it to a 17th Century map from the University of Queensland) but the terrain is horribly simple. It is flat and undetailed. This may be true of the region to a certain extent, but the terrain was more varied than is depicted. It is just, essentially, a flat canvas. Not only that but the ‘edges’ of the map look incomplete and jagged, as though a time-pressed Modder made it. Disappointing.
Textures and models: The textures are ‘different’. They look smoother and more refined than Warband, but this probably has more to do with the character models being less ‘blocky’. The campaign map texturing is good, but it is also plain and a little boring (my opinion only I know). I found it generally to have an unreal feel, as though I were fighting fine-pressed and gleaming brigands rather than dirty villains. Also, many of the looters are wearing this odd (and not historically accurate) coat with a red braid along the chest which makes them look not unlike men in business suits, at least at first glance. The blood textures are far too vague to be appreciated, and have definitely not advanced from Warband. The smoke effects are extremely weak. Almost every musket mod I have ever played from Warband has had better and more realistic smoke effects. The inventory screen is an eye sore, with light bleeding into the already weak images of goods and equipment. The text interaction screens are bland and mostly untextured. Even the most basic of the Warband mods had images on the text screens of the towns and troops.
Sounds: Sounds are standard. They have not even bothered to take out the old bandit threat vocals. I have these polish brigands telling me "I'm going to break you legs' in what appear to be Yorkshire accents. Crazy and Lazy!
In short, this game is nothing more, at the moment at least, than an inferior mod for Warband. For something that has to be paid for, this game is extremely disappointing. Overall score 3/10 and that is being generous. For context, I would give native Warband 7/10 when it was new and untried. Eagle and the Radiant Cross 8/10, an excellent mod. And my personal favourite, Brytenwalda 9/10. Do not buy this game!!!! I heard from someone that Taleworld actually had nothing to do with the development of Fire & Sword. If this is true, they should consider distancing themselves from such a rip-off.
