Sure but it has dragons and unicorns. You do not like unicorns Diocle ?
ToB is a bad game. Its under-performing sells are logical and deserved. ToB suffers from a poor marketing campaign, features removed, unambitious gameplay design and a dubious artistic direction.
Its pre-release marketing was poor for multiple reasons :
First ToB's focus was already covered by Attila. Vikings were the focus of Attila pre-release faction DLC. Irish and Scottish factions were covered by a following faction DLC. Then Charlemagne made playing the Anglo-Saxons and the Vikings (once again) during a timeframe close to ToB. So ToB felt very much like a repetition of Attila DLCs with the additional disadvantage of Attila being a stand alone DLC from Rome 2. TOB also suffered from its release calendar. It was announced and release after Warhammer II had been announced but before it was released. CA created confusion with its Saga thing. Fans already complained ToB looked like a glorified DLC for Attila and CA exacerbated the fears by telling Saga titles are smaller title than "normal" TW titles. After its initial misstep CA struggled to present ToB and its Saga thing as genuine stand alone title. Lastly Legend of Total War certainly damaged ToB's sells when he covered negatively the title, criticizing the title as dull and with too many cut content. To be fair his negative preview was entirely justified.
The content of ToB is not good :
There are too many cut contents. Ambushes were removed for unknown reasons. Character's retinue and skills point were clumsily merged. Religions and cultures taken out even as it should have been extensively covered given the period. Special agents were totally removed instead of reworked. Even diplomacy was simplified. Worse there is barely anything to replace the cut-off contents. Oddly enough, CA kept the technology tree even as during the Early Middle Age in the Britannic Isles hardly looks like a time of innovations and discoveries.
CA and Jack Lusted tried to present ToB as an innovative title where they experimented many thing. It is not really true. For example the unit recruitment with few elites troops available existed in Medieval 2. A title released 12 years ago. Ok you do not need any building for recruitment but this was essentially true for units which only require the main building chain in earlier titles. Despite the smaller focus, individual factions do not feel really unique. The war weariness system of Charlemagne was implemented without change. As a result it ended up doing the exact opposite of its intention : allowing a victorious player to steamroll at will while punishing further players in trouble against the AI. Basically CA distributed different bar to fill or balance automatically. With the patch they are essentially copying the rites system of Warhammer 2. Let's agree its too little.
The battle gameplay is also disappointing. During his recent interview, Jack tried to present positively ToB's battle by claiming the shield wall is presented in an automatic fashion. But in truth CA just reduced the unit spacing and tone down the pourcentage of 1vs1 animations. That is hardly an introduction of shield-wall warfare and it is a shame.
Despite its narrow focus, the game is unpolished. Typically the walls in ToB are a copy-past of Attila walls despite the fact that siege warfare of Late Roman era and Anglo-Saxon era had nothing in common. There is not even an animation to remove battering ram once the gates are breached ...
Overall the campaign gameplay suffered from too many cut contents and a general clumsy implementation of the remaining features.
A final note on the artistic direction :
The artistic direction is difficult to understand. CA choose to cover the British Isles shortly after the Great Heathen Army. The studio intentionally choose to not cover the most iconic viking invasion of England to focus to "what happens after", as CA liked to say before the game release. I think it is a fine idea. But then they added some epic music track including the main one which would have been for fitting for the Great Heathen Army. The game introduction has an ill-fitting modern direction and the game UI a very different style. It feels like there is no coherence in the artistic direction. In my opinion the game misses the mysterious, simple and mythical atmosphere fitting with Early Middle Age (particularly in the British Island).
