> I spent some time trying to come up with a wrapper game; something like a map of a city with all the individual buildings you can infiltrate on it. I’d like there to be an overarching mystery to unravel, or threat to unmask. Figuring out how that should work has been a challenge.
I can see that as being a great game, especially if it would also incorporate the more supernatural elements from Thief (wizard's towers, pagan forests, ancient trap filled tombs). Best of luck when/if you try it out!
Just to throw a few ideas out there:
On the big map, a player could strategize which district (each with it's own level generator, obstacles and items) to play next- depending on what they're ready to handle, or which loot they want. Staying too long in a single district makes it more difficult (e.g. increases guard presence) or eventually temporarily blocks it from play completely. Random events force the player's hand to play certain districts or special levels (e.g. city watch raid the hideout). Occasionally story events hint that a clue/story item can be found in a certain district.
