I for one would LOVE to see the original VT1 maps and DLC converted to VT2. Just like Left for Dead 2 did with the L4D missions, covert the original Vermintide missions/DLC to the Vermintide 2 interface. I never finished all my VT1 DLC. Being back in a VT mood and going to play them now, the VT1 interface is slow and clunky compared to VT2. It’s actually not nearly as enjoyable. Congrats to greatly improving on what you did the first time!
There were some great missions and story in VT1 and being able to use the new careers and crafting system would be awesome to refresh them. Since the theme of VT1 did not include Chaos or the Rotbringers, keep the spawning and such to Skaven only, but include the new Skaven types from VT2. I would love to play through the Fall of Ubersreik straight into the new setting.
And please bring back the Lore Notes that unlock the facts about the Old World. I’ve been involved in the Warhammer world since the 80’s and was heartbroken when the Old World was destroyed. I know most of the info the notes unlocked, though a few little nuggets were new to me. My nephew and step-son started getting into Warhammer because of VT1 and loved the lore. They learned most they know from those notes.
Hopefully this is something you can easily do and will implement. Might help keep some of the online nerd-rage about DLC quiet as well.
