This game is actually not worth it's price. It has what made the Spellforce franchise great, but it's short and i'll risk to say that it has the worst story of all the Spellforce series, based on the cliche that you have to do everything "because it's your destiny". However, if you like Spellforce mechanics you can still find this game enjoyable, and if you like the single player free mode it will be worth it for you.
Beware, however, that you won't be able to play with your friends if they own this game because the servers exist no more. You may try to find a way to play online with a program like hamachi, but I can guarantee that it won't be easy.
Very average for the Spellforce series 57/100
