Since W:A doesn't work, I'm thinking about picking this game up since I heard it's extremely similiar.

similar yet older and worser off.... especially if you have a geforce 6600 videocard.

Vazaka, please check the other thread you posted. Not-surprisingly, Worms Armageddon works perfectly fine with Windows XP Pro; just as well as Windows XP Home.

Worms World Party is not in [official] development. The last update it got was released in 2002 or 2003. Development for WWP has been totally discontinued by Team17. It is soon-to-be merged with WA.
