I finished the game. It disappointed me more than it pleased me. The dark mission remains unresolved; we defeated Biara, but she isn't the main antagonist. The creation of a new Unicorn empire with Frida on the throne is a plot point for a sequel. They created new creatures for each race, so you need to play as them. Otherwise, they just show them off. It would have been logical to make the final part consist of at least 8 campaigns, so you could play as each race, level up your heroes yourself, and not receive them at the end with a set of useless skills and spells. Each player has their favorite spells; some like light magic, and others like dark magic. Overall, the final part is clearly weaker than the previous ones. The Orcs are great, but that's not enough. I would like to see the opinions of other players.
