I don't understand the point of reissuing a game that is still being sold in digital form.
As far as the 3.8 update goes, I doubt that it will ever see a release because as CS said, it's been more or less finished for a very long time now. The fact that it has not been released indicates to me that there is some sort of deeper issue, and being completely in the dark about it is annoying. I'd be totally fine with the update never coming out if DC would just straight-up tell us.
I know that a lot of people are Team17 haters and are not fans of the newer Worms titles, but personally what I am hoping for is a new Worms game. WMD has been out for some time now and it could have been a truly awesome game if Team17 had just put a little more time / development into it and also had a closed beta for feedback. It's not a bad game at all; it just needed more polish. It was definitely a step in the right direction though, getting the series back to 2D, 6 players, a ninja rope more like W:A's (but still far off), etc. WMD is the first Worms game since WWP that doesn't feel like it was made for consoles.
Moving forward I'd like to see Team17 release a new game that stays in 2D, has a *proper* chat lobby system from launch, a proper ranking system with multiple ranked schemes AND clan implementation, a ranking system that doesn't reward grinding so much as getting wins vs. good players, increasing maximum player count to 8 and also adding spectator seats, easy streaming integration, vastly more unlocked/unlimited scheme editing potential (we should be able to edit anything and everything we want), get rid of the crafting system and vehicles, keep buildings, bring back water, include all legacy weapons and utilities (except for ones that are too redundant), detailed stat tracking like we had in Clan Wars, bring back 'physics objects', and introduce new gameplay elements like smoke, different surface types (sticky, slippery, etc), improve the ninja rope and make it as close to W:A as possible, introduce objects that continually pump out some sort of 'liquid' like water, lava, etc. Of course when water and lava come into contact with each other it turns into fresh terrain. I think it'd be cool to have Angry Birds-esque stage elements that can topple over. I'd like to see wooden objects that can catch on fire and will burn completely... and when the smoke is in the way you can't see outside of the smoke. I'd like to see wood and other objects that can float in water. I'd like to see bouncy surfaces like trampolines.. pinball bumpers that kick worms around.. a wormhole item that connects 2 points of the map and lets you travel freely between the two points.. etc etc. I basically want to see a rock solid 2D Worms game that has all of the best elements from the past with highly refined gameplay mechanics and interesting new features that enhance the gameplay.
