Great! I have quite a lot of ideas.
About the story setting, I like the Dark Wars, since I personally love dark and horror themes especially. Also The Fallen Age sounds very good, we could miss Dragons though, but Blackwings could play the main role with cooperation, treachery, etc…
As I said, I have some ideas, cuz I was thinking about the game for a long time, but I am not sure what kind of a game it should be. I have three main genres in my mind. It could be:
RPG - basically something like Drakan in a “text” form. Could be of course made with graphic fight etc.
Rogue like - I am heavily inspired by Darkest Dungeon and Deep Sky Derelicts and I like the idea, but would take probably more time, since I see it as a next level RPG.
I have also been thinking about something Frostpunk (city building survival), but this is the least possible option for me. I have finished reading Mortal Engines book, so I am just influenced by it probably.
Multiplayer is a must. I would like to live with other players in Drakan world. There could be PVP, Coop etc. (which is kinda killer for a city survival)
PS: A card game doesn’t attract me actually (sorry), but it reminds me I like the card system from Warframe.
PSS: Everything is debatable
I would go into deeper details once we choose the genre and settings.
