Ok well no offense but this is probably 400 of the best points you have ever spent because the main draw to this game on xboxlive is the online ranked and player matches which my girlfriend plays everyday almost and shes actually made a few new online friends that she likes playing this game with.
We also bought worms 2 and never play it because we prefer this one.
In point of fact I think this is the one game we bought the most accessories for as well including all but the desert map which I still plan on getting one day.
I hope no one reads this and only gets half of the story because this game is one of the most fun and addictive multiplayer experience on live as well as a very high level of competition.
Maybe you should give this game another play through in ranked and see if you aren't enjoying this game after that because if you aren't then you probably don't even like worms to begin with.
