I want a Batcave that embraces the idea of him building his Batman persona in full, along with some Sherlock Holmes style messes and idiosyncrasies:
- Have the Batmobile’s area have all the kinds of lifts, chains, harnesses, and tools that you would expect to see in a garage, so you can tell that some nights he has to remove a banged up chassis for a new one.
- Have the computer be set up in a chaotic manner to suggest he’s jury rigged up the system as time’s gone on, with maybe a 3D printer and scanner making up a chunk of its mass. And I’d want a table with opened files and photos next to it, where can place down and examine physical evidence, including a microscope and CSI kits.
- An Arkham Origins style workbench, with schematics, prototypes, doohickeys, a blowtorch/welder, laser cutter, and all of it a cluttered mess you can tell is only as organized as Bruce would want it.
- And since he’s not yet progressed enough for true momentous and trophies, I’d give him a cold case room with physical evidence displayed next to the files, sketches, and just odds and ends he has attached to it - like maybe he’s got a Deadshot Rifle he’s half disassembled next to some examined slugs, a League of Assassin’s sword on display next to sketches of other enemies he’s encountered and security camera clips of the ninjas, some Holiday Killer evidence... and maybe, prominently isolated from the rest, a Joker card next to a Red Hood mask.
One thing I really would love would be a lot of evidence of Bruce having decent sketching skills, so he can draw a sketch of his suspects, or design weapons or gadgets, and allow for a vague enough look that it could be real concept art or something entirely different if it finally appears.
