Yeah the only Worms title that is even remotely close to Armageddon is WMD. The new engine restores some of the pixel accuracy that very early worms had, which gave you good information to make clever shots. Around the Reloaded/Revolution years, the variable zoom, blurry pixels and odd feel of the physics made it tricky enough to just make basic shots on target. With WMD you can at least get some trick shots with grenades again.
Some of the items in WMD are pretty good too, like the party balloon, gun turret, sheep on a rope, bunker buster, and that bolt that has proximity grenades hanging from it that I can't remember the name of. The crafting system was ambitious but needs streamlining imo. Picking up items gives a mix of 4 resources and you have to balance them all when spending. Also the crafting GUI keeps closing as phases of the game pass even though it's not your turn yet. Oh, and the vehicles are basically a disaster, they are well implemented but are so good that the game revolves around control of the vehicles while any are on the field. I turned them off in my games pretty quickly because the regular worms weapons are way more varied and fun.
Overall though WMD is the best worms in ages, has Steam matchmaking and a functioning ladder, but still didn't make a lot of momentum. I'm not sure the traditional worms recipe has the potential to blow up huge any more, it just seems like a side game that's great to pull out when you're with friends.
