I agree a lot of stuff is missing, and there is much work to be done, but personally I consider the game to be a success. Other than the occasional publisher like NCsoft(multi-mmos), and Blizzard with Warcraft/starcraft (wich is whfantasy/wh40k) and some of those evil-conglome-hives of studios, no one has been able to develop two videogames that are basically the same, but have enough layers of mechanics and differences to make them both stand apart from each other, without eating away at each others playerbase.
The rejection on behalf of the Vermintiders, is no different than the rejection from Fantasytabletopers when 40k came out, and how to this day, those that play the tabletops religiously, debate on why one or the other is better in both rules/figurines/lore. That has been achieved here. Just as Vermintiders hate on Darktide, Fantasy hates on 40k. You replicated what GW achieved.
If Internet/forums where as prominent when WH40k tabletop was released, and Tabletops playerbase where as large as Steams playerbase, WH40k woulda died on the spot. The amount of fantasy players hating on it, because it was not exactly like fantasy would have generated so much backlash, and on top of that the endless amount negative reviews (from vermintiders/fantasy) would have discouraged a big chunk of people, that are considered hardcore fans today, from buying it, GW woulda been on the phone to China, DMing someone to cease production on any wh40k figurines. We would have never had experienced the amazing universe that WH40k is today.
How does all that relate to the game? Well, you are facing the same dilemma, but in a different medium. Either you kill what makes Darktide stand apart, and turn it into Vermintide, or you accept that you have tapped into another demo/market, and continue working on Darktide, refining the mechanics/gunplay that make it different.
I mean why not replicate what GW did? Some people prefer guns over swords, some people prefer medieval combat over military warfare, you can’t have one product that fits all. Why not develop both continously, with new iterations every 3-4 years, refining melee on vermintide, and ranged on darktide. Why not have Vermintide be the ultimate Melee one stop for fun, and Darktide be the run and gun thrill ride, always focusing on what really makes a Fatshark game, a Fatshark game, the way you just dump enemies for us to slaughter.
Why not have 10 million vermintiders, warring(In a civilized manner of course) with 10 million darktiders over wich is best? Competing against each other to see who kills more during the skulls for the skulls events, working together to unlock skins for the other game, instead of the one they are playing, in teh end just like with fantasy/40k supporting each other, invested in the success of both games, because they undestand that whats good for GW/fatshark is good for them.
With all the tools, guidelines, bibles what not you have already on Vermintide, and will soon have on Darktide, the all-stars(auric level operatives) can focus on new projects, taking risks, while still having a committed long term development for both Vermintide, and Darktide franchises, bringing money to keep the lights on, and keep growing. Maybe even one day with everything you have learned, develop your own IP.
People that might have taken a more secondary role in development can step up, and the addition of new people to the team to fill in the gaps for the veterans that want something more, will already have a guideline, and new blood, might bring in new ideas.
If anything its a New Year, and you should try looking at thing’s in a new way, yes the game is not complete, yes there are things wrong with the store, and there are a bunch of other issues (lets not forget all those pesky reviews on Steam). But the gameplay is there, and once you realize you have actually struck gold, and probably share this point of view with GW, you will see that all this is not that crazy, and that you should be excited, and they should be excited, because all this can end up being a really good thing.
