I understand that this is your opinion, but no offense, do not generalize it. There is a great number of people who were asking for better character customization (in terms of hats, armour skins, weapon skins) since the original Vermintide. You may not share this interest, but please don’t make it sound like everybody thinks the same way or that it should be this way.
People want to look cool and differ themselves from other players. People like to express their style - and we are talking about Warhammer, which has an awesome amount of great looking armours, weapons, heraldry etc.
Some say that it doesn’t matter, since Vermintide is a 1stP game, which I can see the argument, but that doesn’t really change anything. You know how you character looks like, and how other players see it.
This honestly made me chuckle a bit.
Are we still talking about Warhammer, where people buy plastic miniatures which they then paint and play games with? Crazy right?
You don’t have to be a child to enjoy something that looks nice/unique. I am sure you are not that naive. Besides, if there is something that the contemporary game-development culture thought us it is that people are willing to spend loads of money, or grind for hours straight only to get something good looking for their virtual characters (and no, most of them are not children).
I wouldn’t necessarily say that new maps is the main reason why people keep playing Vermintide. The strongest aspect of this game is its unique combat and, to some extent, encounter unpredictability.
Of course, having new maps is great (and I personally think that giving the playerbase the ability to create their own maps would be a very important step), but expanding on the core game is more important - creating new careers for existing heroes, improving the crafting system, giving the player base interesting long-term rewarding goals they could aim towards, while adding new interesting maps in regular intervals (as we will hopefully have now with Drachenfels) - but all this costs money.
The game won’t die as long as there are regular - meaningful - updates that won’t hurt the game (like WoM did - even though it was a good idea, however poorly executed).
In the end yes - we will need the ability to create new maps, but right now, FS is still producing new updates and there are way more urgent issues they need to address.
The way I see it, maps only create “horizontal depth” which is not long-lasting. What we need is a “vertical depth” that would bring something fresh and give players a reason to go back and replay the already existing content.
