Spellforce has everything a mix of RPG with RTS gameplay should have. It's entertaining, it provides a lot of gameplay ... and it is unfinished content wise. The main program begins very good, gets better and better, but after two thirds of the game, the designers simply forgot to "fill in the blanks". No more sidequests, barely existing main storyline, boring hardcore missions for people, who find pleasure in punishing themselves in playing the last third.
Both addons partially fix this lack of content, but sadly, the difficulty level reaches new heights and frustrates many players instead of offering a fair (!) challenge. "Spellforce" could have been a very good game, an excellent game. But its shortcomings are to big to ignore. So, only 3 out of 5 for the potential and the first two thirds of the main program. THIS part is very enjoyable!
