I am one of the few Worms players who actively plays / played all of the Worms titles. Clan Wars / Battlegrounds is actually a very good game once you recover from your initial "wtf?" shock factor, which isn't as much of a shock if you played Revolution as well. Yeah, the rope is vastly different in CW/BG/Rev, but it's still pretty usable once you get the hang of it. The 2.5D nature of the game also causes some issues with perspective and whatnot, but you get used to it. The game actually has some awesome features...
1. Worms 'classes' - being able to choose from soldier, heavy, scientist and scout worms allows players to customize their play style and makes matches a bit more dynamic
2. Dynamic water - a great addition to the series that adds another layer of depth
3. Physics objects - these aren't implemented perfectly by any means when playing online (they show more variety / purpose in the campaign modes), but still fun nonetheless
If you ask me, Clan Wars is the best of the newer-gen Worms titles, and Reloaded is the worst. Reloaded has a beautiful aesthetic, but the core mechanics are just trash, which is sad. The rope is also retarded, especially on the console versions.
