If there was every a good OOS style mission, this is it.
I love this idea. It would be so cool to go through a maze of not just AI but interactive puzzles like an Indiana Jones scenario.
I like the 'idea' of procedurally generated caves but any game that uses procedural tech always ends up using the same exact assets for things. Example, my game that I love, Starbound, and to a certain degree Stardew Valley, both use procedural tech. But every 'new' area is really just a rehash of the same assets that don't really offer anything new to do or see. So, it is new but it isn't, if you know what I mean.
