It's a really nice game, very enjoyable. Maybe a lack of originality in tis new version but i still play it.
I also enjoy very much the skirmish mission and soe new changes about the spice (economy) might just make it better.
The worms are really good at this game, more mobility, comparing to the others from the past games.
The only big problem you can get is the IA can become a little boring once you dominate the game and it won't impress you with new tactics, but it's a problem most games from that time have.
