According to what was communicated by the creative director Ashraf Ismail, Assassin's Creed Valhalla it won't have big blocks of progression on the main story missions. Specifically, the man spoke of the EXP system of Valhalla during an interview granted to Kotaku, who asked some questions about the lessons learned from the two well-known complaints generated by Assassin's Creed Origins ed Odyssey concerning the experience. As we well know, in fact, in these last two chapters the story missions jumped abruptly in level between one and the other, thus forcing players to do a lot of side missions to progress in the plot. Below, an excerpt from the interview with Ismail:
We've been thinking a lot since Origins about progression and what it means to players, so we decided to take a new vision of progression in this new game. In fact, we will see the concept of power and strength more marked, which will increase with the addition of new skills.
Ismail also pointed out that Valhalla is avoiding any kind of barriers in this regard, such as the ones mentioned above which sometimes delayed story missions in Origins and Odyssey. Ubisoft's new work will undoubtedly have a wide range of secondary content available, but if the player's intention is to just continue with the story, it seems that this time it will be able to do it.
As for i booster EXP purchasable with real money, their presence in Valhalla has not been denied and confirmed, however during the comparison it is highlighted how the team wants to earn every single cent that the players will pay for the base game.
