A bit of inner turmoil always accompanies the purchase of the newest Worms game. Do I really need this? I just bought one last year. Ten seconds later: Okay, fine, I'll get it. Despite the general sameness of each title with minute changes to keep things fresh, Team17 consistently makes just enough of those changes to warrant the yearly refresh. Worms Clan Wars follows in this mold, making lots of little updates, plus one big one.
